The last player moved...and everything turned out as planned!

Yippeyah!
I would like to avoid the graphicless server, however then I have the problem that Windows will not hibernate on its own when idle

if Dom2 is run as graphicless, then WindowsXP does hibernate as scheduled.
I am grateful for any hints about this auto-hibernation issue and how I can prevent it from thinking that the inactive Dom2-Graphical-server should keep it awake...
