Error while starting up Wings 3D

[micheus]

Geertvc, even your video card being an old one (2005), that OpenGL instruction should not break it. I don't know what to say, because there is no way to recreate this situation here. I got similar effect when playing with OpenGL drawing for my Heightmap plugin - OpenGL memory was being corrupted by wrong settings I did. (that's not the case of the official release)

Were you using any previous version of Wings3d before and it was working?
Did you download and installed the Development Release of Wings3d?
