- GENERAL SECTION
- ===============
-
- Q. I've found a problem with the WIN-OS/2 printer driver that I'm
- using with my printer?
- How do I get an updated version of the driver?
-
- A. The WIN-OS/2 drivers were not written by IBM, but are licensed for
- inclusion in OS/2. If you need a driver update IBM might be able to obtain
- it for you, but you'll get it much quicker if you contact the supplier
- directly.
-
- Q. How do I run WIN-OS/2 in real mode? Can I run WIN-OS/2 in 386
- enhanced mode?
-
- A. Type 'winos2 /r' from an OS/2 'DOS Full Screen' session, or put '/r' in
- the parameters held for an OS/2 shell object. WIN-OS/2 doesn't support
- enhanced mode and applications that require enhanced mode will not run.
-
- Q. Why won't ScanMan and FotoTouch run under WIN-OS/2?
-
- A. They both make a 4B interrupt call to create a DOS thread. This isn't
- currently supported.
-
- Logitech scanning hardware is normally used by WIN-OS/2 applications
- running in real mode. Note that Ansel (Fototouch's predecessor) will work
- in real mode.
-
- Q. I get DOS Error 5 when I try to run some of my Windows
- applications under WIN-OS/2? What do I do?
-
- A. Boot from OS/2 boot disk, insert disk 1 when prompted. When you get
- OS/2 Welcome screen press ESC. Insert disk 2 and type A:CHKDSK C: /F
- (FAT) or /F:3 (HPFS) where 'C:' is the drive OS/2 was installed to. Repeat
- CHKDSK until it runs without any errors.
-
- Q. How do I start multiple WIN-OS/2 applications from the same OS/2
- desktop icon?
-
- A. Drag a program object from the Templates folder. Set Program to '*',
- set Path to full path names separated by commas for programs that you
- want to start. See Master Help Index - WIN-OS/2 for more information.
- First program listed is incorrectly started twice.
-
- Q. I have the Canadian version of WordPerfect 5.1, how do I run
- FIXWP?
-
- A. FIXWP (see OS/2 readme) doesn't work for the Canadian version. Call
- WordPerfect and ask for interim release.
-
- Q. SHIFT-ESC doesn't seem to do anything under WIN-OS/2. This
- means certain programs (see Attachmate under Applications) can't be
- run. Is there a fix?
-
- A. A keyboard bypass option for SHIFT-ESC needs to be added to WIN-
- OS/2 and DOS settings for CUA (Common User Access) compatibility.
-
- Q. I Get FATAL ERROR 0X0401 trying to start a Windows
- application in a WIN-OS/2 session. What can I do?
-
- A. This problem is caused by one or more of the drivers or font files listed
- in the WIN-OS/2 SYSTEM.INI or WIN.INI file being absent or not
- loading correctly. This can happen if the application migration/installation
- was incomplete/incorrect. Check device statements, or re-install
- application from WIN-OS/2 Full Screen.
-
- This error has also occurred on systems running in XGA or 8514 video
- mode when an application tries to use large fonts. It might be necessary to
- modify the WIN-OS/2 SYSTEM.INI file as follows; fonts.fon= xgasys.fon,
- fixedfon.fon= xgafix.fon, oemfonts.fon= xgaoem.fon.
-
- Q. I have an 8514 display and am having trouble using DDE with
- WIN-OS/2. What's the fix?
-
- A. If you have an 8514 display use DOS Settings to set
- VIDEO_8514A_XGA_IOTRAP to Off and
- VIDEO_SWITCH_NOTIFICATION to On.
-
- Q. Data I put in the OS/2 clipboard doesn't show up in the WIN-OS/2
- clipboard. What could be causing this?
-
- A. Because of the particular data format there may be a rendering problem
- that prevents the reception of the data from the WIN-OS/2 clipboard by the
- WIN-OS/2 application. A private data format used by one application
- could be unusable by another. WIN-OS/2 clipboard issues are covered in a
- similar document to this one.
-
- Q. I'm using the EPSON.DRV WIN-OS/2 printer driver and I get
- duplicate form feeds, can I disable form feeds?
-
- A. The EPSON.DRV driver doesn't provide disable form feed or intelligent
- form feed options. If this causes you a problem you'll need to select another
- driver that works for your printer.
-
- Q. Every few pages my HP DeskJet 500C color printer prints a whole
- page condensed to slightly more than 'thumbnail' size. How can I fix
- this?
-
- A. You need to add [STATDLL] override=y to WIN-OS/2 WIN.INI file.
- Read the read.me file for your DeskJet printer. This file is located on the
- first of the DeskJet driver installation diskettes.
-
- Q. Sometimes when I switch sessions from the OS/2 Desktop back to
- WIN-OS/2 using the ALT-ESC option I find that I have no mouse
- pointer. Is this a known problem?
-
- A. This problem has been reported and logged. Simply repeat the ALT-
- ESC sequence to recover the pointer.

- Seamless WIN-OS/2
-
- Q. What is the difference between a seamless and a non-seamless
- application? Are there any problems running Windows applications
- seamlessly?
-
- A. First realize that the way an application is started (double-click on the
- application icon on the desktop) is the same whether the application is set
- to run seamlessly or non-seamlessly.
-
- When a Windows application is started it is seamless if it starts as a
- window on the OS/2 desktop (imagine the Windows application starting up
- and 'punching a hole in the desktop' so that the application window can be
- displayed) . It is non-seamless if clicking on the application icon on the
- desktop first starts a WIN-OS/2 DOS session, and then starts the
- application from this new session. In this case the OS/2 desktop has been
- replaced with WIN-OS/2 Full Screen (imagine running Windows 3.0) and
- the application is running within a complete Windows environment. When
- the user closes the application, the Windows session is automatically
- terminated, and the OS/2 desktop is re-displayed.
-
- When applications are migrated to the desktop (Setup - Migrate
- Applications from the OS/2 System Folder) they are configured to run
- seamlessly. It is a simple matter to change them to run non-seamlessly
- (click on application icon with right mouse button, click on open, click on
- settings, click on session, click on WIN-OS/2 Full Screen).
-
- Running windows seamlessly is a complicated thing for OS/2 to do
- internally. The known seamless problems at this time are:
-
- - occasional unexpected loss of focus, for example when running Word for
- Windows seamlessly. Use the left mouse button to restore focus.
-
- - no Windows applications are running at shutdown, but upon reboot show
- up cross-hatched (as if they were running when the machine was shut
- down). Correct by closing WIN-OS/2 session from window list. Press
- CTRL-ESC then use right mouse button to close.
-
- - OS/2 gets confused when more than one Windows application is
- running. Selecting an application from the window list (press CTRL-
- ESC) results in the wrong application being selected. Correct by
- changing session parameters for the applications. Do this by clicking on
- application icon with right mouse button, click on open arrow, select
- settings, select session, then click on 'Separate Session' check box.
-
- Q. My display is not VGA. Can I run my Windows applications in
- seamless windows?
-
- A. You will not be able to run seamless windows unless you are running
- OS/2 in VGA mode (or XGA mode with the Video Upgrade package).
-
- Q. Why can't I override the system setting for 'Minimize To' behavior
- for my seamless windows applications?
-
- A. This is a known problem and has been fixed for the first service release.
-
- Q. I created a document icon called 'WordPerfect Document' with an
- association to my WordPerfect program. I double-clicked on the icon
- and WordPerfect started up. After I had finished with the document I
- closed it. When the icon reappeared the name had changed to
- 'WordPerf'. What went wrong?
-
- A. WordPerfect doesn't support Extended Attributes (EA's) and when it
- saves a file to disk any EA's that existed for that file are lost. The same
- problem will occur with all Windows applications. The workaround is to
- save the extended attributes of the file (using EAUTIL /S) before loading it
- and to reattach them to the file after the program has exited (using
- EAUTIL /J). This may be done using REXX. This approach will have even
- more potential when REXX is enhanced to support manipulation of
- Workplace Shell objects.
-
- Full Screen WIN-OS/2
-
- Q. I have changed the settings for my Windows application icon so
- that the application runs in a WIN-OS/2 Full Screen session. Now
- when I close the application I am left with a blank screen,
- except for an icon named 'Desktop' in the bottom left-hand corner of
- the screen. What is wrong?
-
- A. This usually happens if a 'Help' window is opened and never closed
- while the application is running. This is a WIN-OS/2 problem rather
- than an application problem. Click on the 'Desktop' icon to get back
- to the OS/2 desktop and delete the application from the window list
- to terminate the WIN-OS/2 session.
