Summary: How do I save window positions without changing a file's modification d
Lines: 27

I've decided to implement automatic saving of window positions in my
application.  I've tried to cling as closely as possible to the
guidelines expounded in IM VI (User Interface Guidelines).
However some points remain obscure:

1. IM VI says that if the user opens a document, moves its window around
   and then closes the document without making any changes, my app is
   supposed to save the new window position without asking anything and
   without CHANGING THE FILE'S MODIFICATION DATE.
   I implement this with by doing a PBGetCatInfoSync() when I open
   the document file and a PBSetCatInfoSync() after I modify and close it.
   Is this the recommended way?  Is there an easier way?

2. When a document is opened, I check to see if the saved window
   position makes sense for the current monitor(s).  I have a function
   declared as follows:

   FUNCTION WindowInDesktop(VAR windowFrame: Rect): Boolean;

   The function returns TRUE if windowFrame is COMPLETELY ENCLOSED
   in the Gray Region.  But other applications (e.g. the Finder and
   StuffIt Lite) restore the window position even if the window frame
   is mostly offscreen.  What is the correct algorithm?

Thank you in advance for any suggestion.
