I create a dialog program use MFC,the program has a RTT pbuffer render.But I found a very strange problem:when the pbuffer render was doing some rendering,if a window overlay my program’s dialog,my program was crashed,and the crash module is always the “nvoglnt.dll”.
I also write a program that do some rendering in pbuffer use glut library,but the program hasn’t the problem.
Why the dialog based program is crashed but the glut based one is not?Is it the bug of NVIDIA’s driver?My driver’s version is 56.72,it is the newest one that I download from NVIDIA website.I test my program in a FX5200 and a FX5700.
