Hi Axel,

I do. If I don't, then the program won't run in Vista either. As it is it *does* work in Vista, aside from getting a few 'makeCurrent() failed' error messages generating within paintGL(). These occur when I first open the gl context, but not thereafter--whereas the errors I described in at least 1) and 3) have are not related to the creation of the gl context.

Take 1) for example--the debugger indicates that that line causes a segmentation fault within glGetBooleanv (it's top line of the debugger output). This happens when I start the program, before I have created any qgl obects. I take it this means something isn't loarded or linked properly?
