I was. But had nothing to offer. That is common here.

I have mine on KVM, NP. But, IIRC, when I first joined there were some
postings about some KVMs causing this type of problem? Search the
archives. I *think* you'll find this is not unknown and not even that
uncommon. I seem to recall that some brands were mentioned as being more
likely to have this problem? Belkin??? Don't quote me though.
I guess I should admonish you to search the lists first? I know it's
more work, but the list archives are sometimes less silent than this
place. And frequently faster to give you an answer on "oddball"
