Thanks for the info.

Since both my KVM switches were ps/2  and one computer was ps/2 and the 
other USB  it seems it just was not reliable.

Since the machine with ps/2 ports can of course work with USB, my guess 
is that a USB KVM switch would work.

For the time being, I'll just deal with two each peripheries on my desk.

My desk is quite large so this is not a major problem
