wine users - Aug 2008 - I think I messed up DirectDraw.

I tried to run a demo of Hype: The time quest (Windows 95/98, uses directX6 or
some glide3 for 3D stuff) to see if it would work. It installed, but comes up
with a weird "Cannot find a game using directdraw" error. I
uninstalled it and went about my way. While it would be cool to have this run,
that is not my main problem.

Now, I cannot run Jazz Jackrabbit 2 (also windows 95/98--runs flawlessly in Wine
normally), which I know ran perfectly before. Now, it does run, but the screen
is completely messed up with red squares and messed up graphics. Along with this
come a bunch of fixme DirectDraw errors. I get the feeling that the Hype demo
overwrote some DirectX stuff or just started messing with things in general.
Oddly enough, Moonbase commander (windows XP)still works. Is there some way I
can check if my copy of Wine is messed up, and if so, is there a way to fix it?
(using Latest version of Wine in Ubuntu 8.04, if needed)

I would check your graphics tab in wine configuration and confirm that the
settings were not changed, or maybe even consider changing some of the settings,
such as the vertex shader support option, and maybe try "Emulate a virtual
desktop". There's a few things you can try right off the bat to see if
it fixes it.
