Bluetooth prob
A cd of 7.1 for Mac came with it but would not open, then ejected. I d/l version 7.1 for the Mac from the web - installer apparently worked because I saw the Uninstaller. However, the Mac still does not see the MS mouse in Bluetooth. Using the mouse without bells and whistles and it works for basic work. I can get along without all the buttons but I expect things to work as advertised -- this time it did not. Microsoft :-(((
