I know this is petty, but we've just had so many problems with this crazy computer from the beginning that this is further ticking me off. So, I get it - the warranty only covers hardware. Is the mouse hardware? It's about 5 months old and quit working correctly yesterday. It either will doubleclick when I click once. Or it just won't click at all. Or you have to push it really hard to get it to click. I know they don't cost a lot, but just curious if it would be covered under the warranty. We've got a one-year warranty on the system.
