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. > Also may the problem is in that you use the class contructor.

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 feature - Thanks for the tip :) /watson
