Hello Austin,

I can confirm the crash - even with OSMesa.
The CAD app indeed uses OpenGL bitmap support.

Relevant part of trace log:

The crash is just a late manifestation of the failing DescribePixelFormat()
call.

The app wants to know the maximum pixel format index hence it passes NULL
pixelformat descriptor.
Wine doesn't handle this ...

If you fix this, the app runs farther (a splash screen is shown) - until the
next crash
Something MFC + user32 -> NULL GetParent() which looks familiar .. I've seen
this earlier but can't remember the bug(s) right know.
