Here''s my basic scenario: I''m writing a pictures screen saver in OpenGL. The program needs to load pictures as it goes. I''ve set up threads to load pictures in the background. These are the basic Win32 threads (_beginthread). Here''s the problem: Whenever certain functions are run by the threads, they screw up the output. The primary example is gluScaleImage. Anyone have any experience on how to fix this? I''m sure the thread''s finishing before the memory is being accessed for display. The functions work fine if I remove the thread. Thank you sooo much!

That being the case, does anyone know of a substitute for gluScaleImage? Calling this function during my rendering pauses the display temporarily, which is really annoying. I need a function I can call in a thread.
