wine users - Feb 2011 - graphics freeze when one program is calling another program

hi there,

I know, wine with some installed winetricks-packages isn't supported, but
that's why I ask here and don't file a bug-report.

I've got the following situation:

Program A (written in VB.net) runs fine on it self. 
Program B (with 3d-graphics) also runs fine on it self.

Now when program A is done, there's an option automatically call program B
(has 3d-graphics). It does so with
"system.diagnostics.process.start(PathToProgramB)".
Program B then starts normally but then somethin in the graphics (I think it
could be X or even something in the driver) crashes and graphics freezes.

I know that WINE itself cannot crash the entire system as it's a
userspace-program, but could it be that WINE passes some bad code/call along to
the graphics-system which then crashes?

I hope you can help me or point me the right direction, thank you in advance!

greetings 
Snej

P.S.: I'm using Wine 1.3.13 (with winetricks dotnet20 and d3dx9) on Kubuntu
10.10 64bit.
ATI Radeon HD 5770 with Catalyst 10.12

You should assume the opposite: graphics drivers themselves are usually much
more buggy than Wine itself, which tends to use the graphics APIs as they should
be used.

You could try turning off Compiz before anything else, that can sometimes lock
up things in combination with Wine. You could also try getting the latest
version of your graphics drivers from the ATI site if you haven't done so
already, they try to fix the most severe crashes in those.
