I am trying to debug a full screen OpenGL application on windows xp with visual c++ 6 using a radeon 2600xt. I have a problem that whenever I hit a breakpoint the OpenGL window remains on top and I can't Alt-Tab anything to the front. I've been developing this application for some time and have tried several different ATI cards, 9600, x1600, 2600 the result is always the same. When I use an nvidia card I have no problems. Has anyone experienced anything similar? Thanks Boycie
