I recently made the switch to windows 7 64bit. My application works perfectly under Windows XP. It also works if I compile it specifically as a x64 app. But if I try to compile as Any Cpu or I specify x86 I receive random out of memory errors from OpenGL. This only happens when i run it under windows 7. If i compile as any cpu and run it on a XP machine i don't have any issues. I've been compiling everything as x64, but now i'm being forced to compile in 32 bit since some of the libraries i'm using are 32bit only.
I'm running a Opengl 3.2 context on at Nvidia GTX280 with the latest drivers.
Windows 7 64bit and i recently installed all the updates.
