BleepingComputer.com: logitech mouse hiding

Hi I have installed an upgrade from XP to vista on my fathers PC. He has a cordless mouse from logitech and keyboard. The keyboard works fine but I cannot get the mouse to work. I have downloaded the driver from logitech but no joy. Thinking it may be a conflict from changing platforms. Any ideas?

I'm not a great fan of Logitech software - but use it anyway because I use their Trackball and want to assign the scroll wheel button as the "Back" key.

That being said, the best solution that I've found for their malfunctioning software is to remove their software, then remove the device, then reboot and reinstall the software.
