Ok, this is weird... All of a sudden, a couple weeks ago, my system started behaving itself when I switched between two machine on the LAN with my Belkin KVM. Prior to that, switching to my wife's Windows ME box and back to my Fedora Core 3 machine would cause the mouse to go crazy. Well, today that behavior is back, and it doesn't appear to be kernel-dependant, as I rebooted with the slightly older kernel that I upgraded from this week (2.6.91.681_FC3, vs 2.6.91.724_FC3) and after switching back and forth between my Fedora box and my wife's Windows machine, that behavior is back. I'm wondering, if it's not kernel-related, WTF is causing these problems? Why did they mysteriously go away and now they're back? I just don't understand... Seems to me that either there's going to be a problem with the KVM and the mouse or there's not. /me scratches head!
