I worte a program using opengl that draws a circle. When I run it on my computer it works fine, but when I try and run it on my friend's computer (vista), the program crashes giving a message relating to DEP.
My friend tried disabling DEP on the program, but vista didn't like that and wouldn't allow it.
I have the following files added to additional dependenices of the input page of the linker:
opengl32.lib glu32.lib
