I was wondering if anyone had heard of a fix this problem. After installing the software for an Xbox wireless gaming receiver, I attach the device as instructed. When I do, my Logitech G7 mouse freezes up until I reboot. I have seen others with this problem on Logitech's forums, but I have yet to see any fixes. Microsoft's support has been no help so far. I assume the issue is driver related, as others with different system setups also have the problem, but I don't know if it is a Logitech driver, or Microsoft...or whether a fix even exists for this problem. Thanks for the help!
