This is weird :) It worked when I removed the & (thought that I tried that
;). Now I just can't remember why I put it there in the first place. I hope
it wasn't importent ... well I will proboply find out when some of the code
dosn't work.

I knew about the __sleep() and __wakeup() but not about the returning of an
array containing the names of the varibles that needs to be stored. Cool
