Oh dear.
Can you temporarily completely unplug the KVM, and put everything back
as it was (with the power off, of course). If that doesn't help, then it
sounds as though the KVM has damaged your mouse.
If it does ... erm, are you sure that you've kept the mouse and keyboard
cables the right way round everywhere? It's very possible that the
"mouse" output from the KVM is connected to the "keyboard" input on
the
PC, which is something that is *mostly* detectable by the motherboard.
What happens if you plug the keyboard and mouse into the Fedora box and
just use the KVM for the monitor? One other possibility is that the KVM
is doing something odd with the PS/2 protocol (or sending current down a
wire that it shouldn't be sending current down).
What happens if you swap the Windows and Fedora outputs on the KVM?
I'll see if I can think of any other weird suggestions to make!

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
