Have you tryed using the soft switchs by pressing scroll lock twuice and
then the space bar
You get a menu of the systems connected and really don't need to be near the
kvm switch. You can also use it as a quick view scroll of all the systems.

I have noticed that with these switches they somtimes
freeze the mouse and keyboard if you are sending mouse
commands while switching.
I was recently putting our switch through some rugged testing
and figured that I really need to be patient or use a
slower process while switching. I now make sure that I am not
touching the mouse while switching. Let me know if the mouse
and keyboard still freeze while trying this movement.
Not a solution - but a workaround...
