sorry about necro posting, but just saw this thread ^.^'
and thought I'd post a possible answer, tho im sure you found this out by now but to help anyone else who happens by it like I did..

not sure ur OS but ive read that in windows 'gets' seems to block the code. So you'd have to find an alternate I/O. You could try threading 'gets' tho, Im having trouble with threads myself and cant be too much help with it lol
