Crashed windowed OpenGL programs leave black square on a screen (Windows guests)

[Max]

If an OpenGL application crashes (windowed mode), the black square remains where OpenGL drawing area was. This square can change color if something from the host OS was above it (in short it is just not redrawn). There's no way of removing that square except turning virtual machine off and starting it again. Screenshot is attached. You can see two weird areas on a screen.

That shouldn't really happen unless there's windows dialog telling something about "an application has crashed...bla bla..do you want to send crash report to microsoft" behind that opengl area in the guest. Pushing alt+f4 in the guest should get rid of that dialog as well as corrupted area. Please reopen ticket if alt+f4 wouldn't help.

I tested further and here's what I found:

1. For debug executables the dialog with suggestion to debug with Visual Studio 2008 appears. Closing it with Alt+F4 leaves corrupted area.
2. For release executables no dialog appears (neither Visual Studio, nor standard Windows one), the corrupted area sometimes disappears like it should, sometimes not (chance is ~50/50).
