Debugging nightmare - advice?

Okay oops... "times" appears to be a C library function.

That's why it's good practice to be more descriptive of your function names. If you'd have used BrickBreakerTimes instead (or whatever your program or library is called) there's no way it would have conflicted

Thanks again for your suggestions and I'm not surprised no-one guessed what was wrong; it took me weeks!

Kinda hard to guess when you posted no code. If you are fishing for answers in a coding forum, best to put some bait on the hook.
