[Wine] Jagged Alliance 2 crashes within first seconds running

[Thrillboy]

Hi everybody,
I'm running wine 1.3.5 on ubuntu 10.04.
I can play WoW, SC2 and WC3, but Jagged Alliance 2 crashes all the time.
It's just this error message:

> err:seh:setup_exception_record nested exception on signal stack in thread 0009 eip 7bc72bb0 esp 7ffdbc7c stack 0x232000-0x330000
> 


It also says this at startup:
fixme:x11drv:X11DRV_desktop_SetCurrentMode Cannot change screen BPP from 32 to 16

I get this message for Starcraft 1 too (from 32 to 8). It runs in a small window, but doesn't crash. Maybe somebody got a fix for this too?
I have an Nvidia card and sound is set to alsa/full.[/code]
