- For anyone who may be interested, I solved the problem.
-
- It turns out to have been a problem with the vertical refresh rate:
- The new monitor supports 640x480 at 72Hz, so that's what I had my video
- card set to. However, the OS/2 driver screws up fullscreen OS/2
- sessions if the vertical refresh at 640x480 is greater than 60Hz.
-
- Oddly, the OS/2 driver works better at 72Hz at 800x600. Fortunately, I
- can have both. (Even more oddly, DOS likes 800x600 better at 60Hz; again,
- this is no problem--OS/2 and my video card's software configuration
- utility let me have both refresh rates at the same time.)
