Hi. Right now I'm running *with* the KVM switch but having the UCB -> PS/2 adapter replaced with a Y-cable, so both the keyboard and mouse ports from the KVM switch are direct (passive) connected to the laptop's standard PS/2 connector. So far (a couple of hours) all works much better :-) So this post might very well be the last one on this issue.
