[luau] WinXP trick

[gutierrej001 at hawaii.rr.com]

if you want to pay a prank on somebody that is using XP on an LCD monitor at
1280x1024 resolution, invert their screen by pressing Ctrl + Alt + arrow keys
to rotate their screens upside down, left to right and viceversa.
it only works on LCD monitors tho'I tried it on CRT monitors but didn't work,
also tried it on Win2K with no results.
so if you wanna get back at your co-workers who have an LCD monitor you can
do it this way.
Have fun!!
