Compulsive Puzzler

I've mentioned before how much I enjoy puzzles. I suspect that this is part of the reason that I'm a relatively good programmer. There are downsides though.

Take tonight, for example. I spent a couple of hours working on my laptop computer because the audio wasn't functioning properly (or at all, for that matter). I finally had to just put it down because I was getting too tired.

I'm still itching to fiddle with it and make it work right. Sometimes, though, you just have to let it go.

So, what situations bring out the compulsive in you?
