heh, well easy solution to the problem is to just use it and see what happens.
Yeah, I mean, feel free to use threads but don't be surprised when your users are reporting weird, hard to reproduce bugs.
I'm writing a C++/Windows application right now that seems to be in the perfect spot to use threading. I almost started coding them in and a voice in the back of my head said, "Why not use idle time instead?" So I'm backing away from the threads and am going to manually do the processing in idle time (WM_IDLE).
Don't use them unless you are absolutely confident that you know what you're doing. But I know that will fall on deaf ears, so enjoy!
