I've found it.  This will apply to any case where you would want to
disable the wheel mouse detection in NT.  For archive purposes, here
it is:

I see that this flag exists in -STABLE but is undocumented as of yet.
I'll give it a try.  Luckily this problem is not too common since I
rarely use the second user on the other KVM switch.

The 4-port OmniCube on my desk only has version 1.5, but that probably
doesn't matter (how would I upgrade it?  I have a ROM burner).  I
can't find the firmware version on my OmniView Matrix.  The only
caveat with these two KVM switches hooked together is that it is a
real PITA when I hit Scroll Lock twice to change consoles on the
remote KVM that sometimes the local KVM will see the same sequence and
think I want to change consoles on it instead.  I wish there were a
way to disable the keyboard shortcuts on the OmniCube and just use the
front-panel button.
