It’s the battery, stupid

My wireless mouse started acting all ragged and jerky. It kept freezing up the minute I wasn’t using it. So I cleaned out the contact points, reloaded the software, muttered about people who might have used my computer while I was out and downloaded something that was conflicting with it, decided that the MacGame I tried to buy had a virus and finally resorted to beating it on the table.  Turns out it needed new batteries. Such old fashioned technology for such new fangled stuff.
