We get this on our LAN all the pigging time! The students think it is oh
so funny to invert the sceens. There is a combination of keys you press
(its a "feature") involving the arrow keys and either control or alt - I
can't remember it off the top of my head!!! Search google for it - thats
how I find it. If you haven't solved it by monday when I'm back in the
office I'll look it up...
OK, I found it
I'ts a feature of the Intel Extreme Graphics set (which we have at work)

16. Why does my display suddenly turn upside down when playing certain
games?.
The capability to invert the display is a feature of the Intel®
Extreme Graphics that ships with i845 chipset PC's. Rotation is enabled
by default and is activated by the default key combination
<ctrl><alt>down, hence why the display may rotate when playing certain
games with the keyboard. If you are experiencing this problem, you can
disable the rotation feature.
To disable rotation, right click the Intel Extreme Graphics icon on the
taskbar, select Graphics Options, then Graphics Properties. Click on the
rotation tab and remove the tick from the enable rotation box.
Alternatively it can be accessed from Display Properties - Settings -
Advanced - Intel Extreme Graphics - Graphics Properties.
