Weird

I own an HP LT, 15.6" screen, about 2 years old.
I have an AOL account and when I go to close the whole window on ANY application, I can't just put the cursor arrow anywhere on/in the box, it MUST be at the very top of the box! WTH? It just recently started doing this. Does anyone here have a clue to what's going on?
