hey whenever I flip my mouse (lift it up and give it a turn) twice or leave it 4-5 seconds in this position it stops working. I have to reconnect the G5 to make it work again. It doesn't respond, not even the buttons react. OS: XP Media Center Edition, Dell Inspiron 9400 (notebook). The touchpad is "disabled". Well the driver's process but it's still working. Is this normal? Another thing is, I don't do it often, of course, but just out of curiosity, when I lift the G5 and then let it drop (my hand still holding the mouse) and the mouse trembles, the sensitivity changes. It doesn't respond to movement for one, two seconds and then the sens is a different (lower) one. I need to end 'setpoint.exe' and restart it. Thanks for reading and hope some of you have a G5 and can tell me if it behaves the same way. edit Should the mouse be "damaged" I would like to change it as I only have it two days, if it is a G5 bagatelle then I don't care and can live with it.
