In windows 98 SE. I create "fullscreen" window with WS_EX_APPWINDOW flag. Then I choose pixel format and create OpenGL context. After window is closed I release OGL context. Very often I 1-1000 access violations in GDI32.dll. I even download some examples from internet and they operate the same way and I get the same bug. What I do wrong?
I used GeForce FX and Radeon 9600XT video cards. And the last drivers.
