- I have this same problem, but I don't have a solution. I did some
- experimenting and it appears that normally, OS/2 intercepts Alt-Home
- to allow the DOS session to switch between FS and Windowed. But
- after pressing Alt-Esc or Ctrl-Esc from a FS, OS/2 does not intercept
- Alt-Home anymore. Instead it give Alt-Home to the DOS session! This
- is why switching between FS and Windowed is impossible for that DOS
- session until you kill it. Of course, I don't know why OS/2 is giving
- the Alt-Home scan code to that DOS session...
-
- Here is a copy-and-paste of a mini-program I made from a DOS session:
-
- E:\>debug
- -a
- 10D3:0100 mov ah,10
- 10D3:0102 int 16
- 10D3:0104 int 20
- 10D3:0106
- -g=100
-
- Run this program. Press Alt-Home -- this switches between FS and Windowed.
- The mini-program is still running because it is expecting a keypress. At a
- FS press Alt-Esc or Ctrl-Esc. Return to the session. Now press Alt-Home --
- this ends the mini-program since OS/2 gives Alt-Home to that session.
