actually a terrific mouse

great mouse. handy good to use ind very convenient (for slide on and off). unfortunately caused the mouse with me regularly blue screens. as there is no driver available from Sony itself I can do about that little. (All updated driver on the PC - no improvement) under Win 7 64bit with Centrino N 2230 very frustriernd. will still try a BT dongle (which the intention is not necessarily because I want the usb slot actually save with the mouse bt) e, and if that does not help, send the mouse back. a pity because I think otherwise really great.
