Logitech cordless mouse keeps sticking/freezing?

This has been going on pretty much all day. It'll work fine for a couple of minutes, but then it'll freeze for minutes at a time, or when I click on something, the cursor will stick to it and drag it. I recently changed the batteries but that didn't do anything. I also restarted my computer, but that didn't help either. I don't have any viruses and my computer can't find anything wrong with it. Please help me, it's really irritating!
