Strange OpenGL crashes on some PC's.

I had my MS Windows OpenGL application
runnig and it runs alright, but on one
PII, G-Force machine, where it rises access violation exception when
inside and OpenGL internal code.
However, first two times I start (and close) the application it works fine. The exception comes only when the application is started (and closed) more than twice.
Please report the similar problems you had,
and please give possible solutions.

Sounds kinda like the program which you are runnign isnt shutting down properly and hence causig errors after it has been run a couple times (trying to use the same resources or somethign like that).

hope that helps a little.
