1: If your computer clock is on the 31st of December (or you just changed it to that), open FL Studio and look at the title bar.
You'll get a funny message, same style as the one on christmas (25 december).
Tried on Windows 2000/XP with FL 5 and 6 (probably also Fruity Loops 3).
Works on FL Studio 7 too ;) Air - Jul 11 2007 2:22PM
