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" problems. > <snip sig stuff> HTH -- Bill
