Nadya-

>I think you're right. I really should have already switched to another task. But it is my nature. I hate unsolved little problems and I was hoping to get this resolved very quickly. In fact, I almost finished it, but then we had a programmer's meeting. Right now it's a lunch time, so I hope to get it done and move on.

I hear you. I'm stubborn, too, and am prone to get stuck on what turn out to be unimportant challenges. I guess everyone eventually learns their own way of not getting sidetracked. And, with that, I'd better stop being sidetracked and get to work myself. ;-)
