What I got was flaky/jerky mouse like when you force it to use the wrong protocol. I couldn't find a protocol that I could force (instead of auto) that worked either. Wasn't important to me since they are really headless rackmount boxes and I was only doing some testing anyways and it's a noname kvm that I don't have any reason to have lots of faith in it being high quality, so I didn't bother reporting anything. But seeing this thread I figured it might be noteworthy. note: Freesbie 1.1 is 5.3-p2 Brian K.
