    Re: Various reasons why OpenGL wouldn't work

    Ok, when I was doing OpenGL on Win32 with 2 cards (years ago but on XP), XP couldn't handle 2 cards and have acceleration, simple as that. Could be the same problem.

    Re: Various reasons why OpenGL wouldn't work

    With wxWidgets you have to compile OpenGL support into the library, it is possible that it's not been built with it. Did you compile wxWidgets yourself or use the prebuilt libs?
