InControl Tools (ICT)99:
InControl Tools 99 shortcuts require a system reboot to take  
effect when running under Windows NT.
Diamond ICT99 "Internet Sites" popup requires IE3.0 or above or 
Netscape Communicator 4.51 or above.

ICT will not be fully functional with COMCTRL32.DLL version
4.70 and earlier.  This may impact Windows NT platforms. The
problems experienced will included :

   1) The InControl Desktop Properties will not execute.
   2) The InControl Desktop Manager will not execute.
 
 To resolve this issue you can do one of the following:
   1)  Install a later version of COMCTRL32.DLL from the Microsoft Web
       Site.  It is part of a self-extracting executable (50comupd.exe)
       which can be downloaded from Microsoft's webpage through the link at
       http://support.microsoft.com/support/kb/articles/Q186/1/76.ASP 
       Download the latest version, currently select the option  
       "Download 50comupd.exe (x86)" 0.49 MB.
   2) Install Microsoft Internet Explorer 4.0 or later.
