Scott and all

No so helpful after the fact but, after several experiences of this type, I
have finally made a box just for demoing software. I was tired of screwing
up my system registry among other things. I kept an old machine when we
upgraded and use that. I really needed to make a disk image so that I could
restore it to a default position if I needed to but did not think that far
ahead. Anyway, if you have an old box around it is probably worth doing.
You can get a simple KVM switch from Linksys for under $100 and as long as
you use good cables you should not degrade your monitor signal that much.
When I finally get around to installing web based mail etc here then I plan
to use that box as my "office box" and keep a separate machine for CAD and
$$ work.

I have to say that I like to support startup software companies as they
often have good value. It does come with some risk though. Also it is
often a problem with the vagaries of Windows although this one looks to have
been a somewhat significant oversight.
