OpenGL My OpenGL program and Radeons

I've given my game to about 10 people so far and the first nine it worked perfectly. Then I gave it to my 10th friend and he said that when he opened the program it would crash and a windows warning window ( the kind that asks if you would like to send a message to windows about this problem ) would show up. I asked him a bunch of questions, and the only thing that I could tell about his computer was that it had a Radeon 9800 where as all of my other friends had some type of nVidia. I can't figure out the problem. Why would my program not run AT ALL on one person's computer, but run fine on all nVidia based comps? I would prefer not to show all of my code, but for the most part, the creation of my OpenGL window is almost the exact same as lesson 1 of Nehe productions.

without any code its going to be practically impossible to help you.

the only two things I can think of are;
- you are using an extension he doesnt have
- you are assuming things about window creation which dont work on ATI cards

Are you using extensions? If you load an extension that's not supported by the video card, and try to use it, your program will crash. This is because the function pointer returned by getprocaddress([function name]) will return 0, and you can't call a function pointer with the value 0.

I'm not sure I know what an extension is. Can you give me a few examples? like is GLUT an extension?

Ok, I'll post my main.cpp, but its a good 800 lines of code...

If you don't want to release the source, you could try posting a demo with executable. A lot of people here have Radeons (me excluded), you could be able to find out if that is indeed the problem.

BTW, congratulations on actually completing a project! That's something I've never gotten around to doing my whole life [rolleyes].
