- I have the exact same problem as you describe. I also have an ATI graphics
- ultra. Machine is a 486DX2 50Mhz ISA with AMI bios. One thing I noticed is
- that the only problem is that the screen is messed up. You really are in the
- correct directory. If you create a file via a DOS command (typing blind
- since the characters don't show up) it is in the directory the session is
- supposed to be in, not the directory shown in the screen command prompt.
-
- You can avoid this problem by toggling the values of the
- VIDEO_SWITCH_NOTIFICATION and the XGA_IOTRAP settings for all Full Screen DOS
- and WinOS2 sessions. (Sorry I can't remember the exact settings or the
- setting values but I'm not at my OS/2 machine now.)
-
- However after making the above setting changes I have a different (but less
- disastorous) problem. When I want to switch from the WinOS2 full screen
- session to the OS2 desktop I click on the OS2 Icon. My keyboard and mouse
- now lock up for just about 13 seconds exactly with no disk activity.
- After the 13 seconds the switch to the OS2 Desktop happens and everything is
- back to normal.
-
- I'm curious if you have similar pause in your system after making the setting
- changes.
-
- Does anyone know how to solve these problems?
