Today my mouse @work stopped working because of a loose contact in the cable. It was a four year old MS Intellimouse Explorer. Unfortunately this defect is not repairable, because it is not possible to open the Mouse. So I am now looking for a good replacement. Requirements: USB, 3 Buttons and a Wheel. Preferrable not from Logitech or Microsoft. And i don’t like the wireless mice that require an extra battery.
