- I have EXACTLY this problem. I haven't tried to alt-home a dos window
- BEFORE starting my first full screen app, but everything else is
- familiar. I thought I was going mad- nobody else seemed to have this
- problem. What the HELL is tseng doing with their chipset docs? How many
- ways can you put their chips into a SVGA card? I have a genuine Tseng
- Mega Eva, and the sods won't even release their generic drivers- they
- give them to orchid, and the other manufacturers, who hack them into
- card-specific ones. Everybody is reporting different problems. Anyone
- know any good vodoo dances I can perform before I try out the next
- driver release? I'm ready to try just about anything...

- I've tried that half a dozen times- varying which modes I change to with
- vmode, and also which mode I run 'svga on' in. If I'm REALLY lucky, it
- clears up the problem- for one boot cycle. After that, it goes back to
- 'normal'. (I've also heard a rumour about turning off ansi.sys in the
- dos session- doesn't seem to make any difference to me.)

- I've got the latest versions too. (But I've NEVER experienced any traps,
- even with the old ones- maybe I should try them again?).
