Query: Never Operated Properly

In spite of ConnectPro's very conscientious service and hours of my own work, this KVM never operated properly in my relatively simple system (a Lenovo laptop using Vista and a Dell desktop with XP). While the laptop operated fine using the KVM switch, the Desktop keyboard would regularly malfunction making it unusable and the hardware wizard would attempt to reinstall software every time I switched the KVM. Finally, I could simply not afford any more time on the switch and am relegated to using separate keyboards and mice for each computer.
