Well, IMO, I always like having solutions stored permanently on forums and Q&As.
I know I'm insinuating myself into a two-person conversation in which I am not involved, but I tend to agree. If you have this problem, there is a very real likelihood that others have had (or will have) the same problem -- and may need just the answer provided in this thread. It would be a shame if they couldn't find the answer here because it was removed.
Quack, swallow your pride, and allow this thread to remain. And, if you wouldn't mind, please edit the title of this thread to something more descriptive with regard to your original question (something along the lines of "Testing whether rectangles overlap each other" or similar). (I could just do this myself, but I would rather allow the OP to do this himself.)
I know you may feel embarrassed that you asked a 'dumb' question -- but remember, not only is this question not 'dumb', the conversation stemming from you asking it in the first place may help someone down the road. What would be dumb would be if that person never got the answer he was looking for because someone else who asked the same question thought it was dumb.
