Hi all: I have been having a weird problem with my Microsoft wireless mouse...I'll be using it fine then all of a sudden I will click on something and a whole area is automatically highlighted (I didn't want to highlight just click on an area). It continues to do this where ever I click until I completely shut down the computer and when it comes back up everything is fine again. I have had the mouse for about 8 months now and have not had any problems until recently. It generally happens in excel, but I have had it happen in word also. I have tried new batteries, tried re-installing, and even turned the receiver updside down as suggested in the literature provided but nothing seems to help. Any ideas?
