Thanks James,

I'm pretty sure the keyboard and mouse cables are plugged in
correctly, the keyboard works fine, but I will check tomorrow (these
boxes are at work). I've tried just plugging the mouse directly into
the Fedora box with the same results. I will try swapping the inputs,
but, the more I think about it I worry that the KVM did somehow damage
that Fedora box's mouse input. Let me know if you think of anything
else I might have done wrong/setup strange.

Thanks,

Tony
