Ok - WinNT 4.0 sp6, Visual C++. I have created a COpenGLWnd class, derived from CWnd. When my scene redraws (10 fps), it does not clear the previous image. I am using double buffering, and I am calling glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BITS | GL_ACCUM_BUFFER_BIT) with a glClearColor( 0, 0, 0, 0).
Any ideas as to why it is not clearing the previous image?
