dewd: you know I like your code alot.. (I don't allways get what you mean but autoIt seems to understand you so the problem here is me)

maybe it's interesting to explain the people in these forums how you do it.. I have no clue on how you start building a screensaver..

(you're on your third or fourth screensaver) :whistle:

I mean give a man a fish and he will eat for a day, Teach a man to fish.. you know what I mean..

He posted source code. So you can learn from it.

@Your sig: Tell man about a word and he will change one. Give man dictionary and he will learn for life.

It is not alot, but a lot. It is not allways but always. It is not autoIt but AutoIt. It is not dewd, but dude (if I guess right :whistle: .)

Get yourself a dictionary!

I can do signature me.
