Cordless mouse Vista Home Premium

Periodically my Logitech optical cordless mouse seems to stop working. The
red light is on underneath as usual, the batteries are fine, but the pointer
just freezes and I have to reboot to get it to work again.

My (corded) keyboard is always ok.

If it matters, the little transmitter box for the mouse is USB.

I never had this problem in XP Home, using the same mouse.

Dunno if it's related, but I sometimes have the same problem with my
Microsoft Media Center remote.

Thanks
