I don't think I told you last weekend that we figured out the issue with my new cordless mouse. It only acts up when Nettl and I are doing our individual computer stuff sitting together on the bed.
We have the same make o' mouse and if they can see each other, mine goes all schitzo and starts running around in circles with his tail up. We've thus decided that mine is a boy mouse and hers is a girl, and as long as we don't let them know the other is nearby, mine behaves quite respectably.
