Re: FOX 1.7.78 OpenGL not working?

I have used VMWare (VM Player) and have had trouble with 3D applications,
such as Altium (PCB layout software) - getting the same "black window" as
you see.  This was the Linux-hosted version of VMplayer, running a Windows
7 VM.  I don't use VMplayer under native Windows, but I would imagine it
has the same problems accessing the graphics hardware.

I would not blame FOX for any 3D problems in that environment.

Not really relevant to you as a Windows user, but I have had more success
using Wine (Wine Is Not an Emulator) to run windows 3D applications under
Linux, than trying to use a VM.
