Could someone please tell me why, around 5pm every day for the last couple of weeks, my wireless laser mouse stops working when it’s on the mousemat, but if I take the mousemat away, and use the mouse directly on the desk, it works fine…

I could understand if it just decided it didn’t want to work on the mousemat, or didn’t want to work at certain times, but specifically at a time, and specificaly on the mousemat. It’s confusing, and REALLY annoying.
