I purchased this mouse to retire a 10 year old unit that was requiring new batteries every couple of days. The mouse is principal used for AutoCad and requires programable buttons. The problem with this new mouse is it does not allow the "Esc" key to be programed. This key is essential to operating AutoCad. Microsoft called me after I contacted them and said they were working on the problem. I have not heard from them in month.
