I just started playing with VMware-server-1.0.5-80187 on a 64-bit
CentOS 5 system system, and am having some issues with the hotkey
switching.  Running the vmware-server-console via an ssh
connection from a PPC Mac Mini, it doesn't recognize the ctrl-alt
sequences, which isn't totally surprising as I'm using a PS/2
Microsoft Natural keyboard on a KVM switch with a USB->PS/2
adapter.  When I try running it directly on the CentOS system's
console through the same KVM switch, it doesn't respond either.

I have installed SCO Openserver 5.0.6a on a virtual image, and
that seems to be working OK (my primary object now with VMware is
to have a fall-back when customer's OSR5 system's hardware goes
south).  I have had at least one situation where it didn't
recognize the CTRL-RightButton sequence in an xterm running on
the OSR5 image.

This is a CentOS 5 system with ``yum update'' reporting that
everything is current.

The system has 2GB RAM.

Once at a social gathering, Gladstone said to Disraeli, I predict,
Sir, that you will die either by hanging or of some vile disease.
Disraeli replied, "That all depends upon whether I embrace your
principles or your mistress".
