It sounds like the device isn't buffering up the scroll locks
like it should.  If the belkin is going to sniff some special
key sequence off the keyboard, he should queue up the sequence
such that if <scroll><scroll> is keyed it remains in the
kvm for some set timeout waiting for an up or down key
sequence.  Further, if the proper sequence *is* keyed, it
certainly shouldn't be sent down to the connected pc (besides -
which one do we choose to send it to?  The prior connected
one, or the new one?).  All in all it seems to be a bad solution to
the pseudo problem of "how can the user swap machines without
having to touch the kvm?"  Stick to the buttons on the box
and hopefully this will go away.

As an aside, the other OSs probably see a scroll lock on, scroll
lock off - if they interpret the keycode at all.

Cheers,

Sam
