    I get a black screen instead my view

    Hello,
    please help me to solve this problem.

    I'm writting an MFC/OpenGl based 3D CAD program and on one
    computer I'm getting a very strange beahvior.

    each time I perform a redraw of the opengl vindow I get
    a black window then
    a gray window then
    the correct view then
    a black window then

    in random order any ideas to were I've to look ??

    On one other computer everithing seems to works fine.

    Thanks
    Giuseppe

    many possible problems, i can only give you wild guesses without further information

    -wrong draw buffer
    -probs with swapbuffer
    -clearbuffer somewhere were it doesn't belong


    hmm no more ideas right now
