yup, it's a pretty common thing to have happen when dealing with old
(and even some newer) kvm switches. At my last job I discovered I could
regain mouse control by unplugging the mouse from the kvm and plugging
it back in again. Worked every time. I've seen some kvm switches with a
little button that allows you to do this via the button, although I've
not used one to be able to tell if it works.
