My Microsoft Intellimouse Explorer 2.0 is now about 3 years old. It's comfortable and easily programable for lots of functions. I get about 60 days from a set of AA's. Lately, though, I've found the mouse erratic. Low signal strength pops up once or twice a day and the mouse becomes all but useless. I've removed any RF devices from around the unit including my cordless phone. I can't figure out what makes the signal strength deteriorate like that. Any ideas
