On starting up the Iyonix this afternoon I found the KVM remained switched to the PC, which was the last one shut down earlier. I had assumed that when both computers were off it would automatically switch to whichever was booted first, but pressing the Remote switched things fine. > If you can't return the KVM, does the unit also have PS/2 outputs (Some of > the OmniViews do IIRC) If yes, then use a USB to 2xPS/2 adaptor and the > problem is likely to go away!

Once I had done this the problems cleared.
