The property added by WinVNC is destroyed whenever the hooks are removed
from the system - this occurs whenever you change desktops under NT, and
whenever all VNC connections have gone. If a Delphi app ran immediately
after a VNC connection had closed, it may well be allocated the same prop
number.

It may happen while the session is connected simply because Delphi has been
run between two VNC sessions and so has grabbed the *old* VNC atom, leaving
the new VNC session to use a new one. If VNC had incorrectly left
properties atteched to system windows then Delphi would then get confused.
