I've now checked and everything on that Forum thread I had already checked,
except Windows Aero which I use. Changing that made no difference two either

Adding to above, - for me, always fails when VRPC was minimised before
hibernation, but not in either of the other two cases. The VA thread shows it
has varied from user to user. It has varied for me, too, on previous machines

I always hibernate from near full screen. I set up a shortcut for hibernation
from full screen, but it doesn't seem to get sent to windows for execution if
VRPC has full screen.
