- This sounds very similar, though not identical to an ongoing problem that I
- have which my OS/2 tech support guy has not been able to iron out for me.
- Someone else, however, has called them with an identical problem to yours
- and they got him back up and running with some odd playing around of SVGA
- on (to make a long story short, they told him to power down HARD after running
- SVGA on while still at the DOS prompt). Call Boca Raton for better info.

- How can you tell if you are running in Interlaced or NOn-interlaced mode?
- What are your dip switch settings (and what monitor are you using?) I
- am using a Sony 1304 and my OS/2 full screen is squashed and elongated
- whenever I start or switch to a session (it looks like I waould have
- 3 rolling prompts if it would roll, though as the screen is cut into 3 sec-
- tions). Tech Support suggested running PSMode before running SVGA ON and
- selecting the highest resolution setting and, from that, running SVGA ON.

- Ah! Something for me to try.
