I have Logitech's cordless desktop EX110. When I had Windows Xp installed everything worked fine. However, I made a partition and installed Vista. Now when the boot selection screen pops up, the keyboard and mouse do not work. However, once the OS loads, both work again. Right now I have the receiver plugged into the USB port but have tried with it plugged into the PS2 as well with the same results. Also, all drivers are installed. Is there anything I can do to avoid this problem? Its a real pain to have to use 2 keyboards.
