A small number of users with XP machines report that an app I am developing crashes on startup in the following way:
- An OpenGL context is successfully created, via wglCreateContext
- The app makes a few OpenGL calls to set up the context (glEnable etc).
- Then, at the very first call to glVertex2f, the app suddenly exits (no error window is displayed)
I believe that this is graphics card related, because the app runs fine with a software OpenGL context, even on the affected machines. Incidentally. one such affected machine has a 128MB Geforce FX Go5700.
If anybody could provide some insight into how to cure this, or to why this happens, or to steps I might take in diagnosing this further, I would be very grateful.
