Thanks for the tip.. I overlooked it, even though i looked very hard.. (i'm used to use shortcuts).
Why are there 3 different options then? 1, 7 or 35 passes? I guess this means it overwrites the file 1, 7 or 35 times?
oh, Arden, i knew from apple.com os x preview that it existed, but they don't tell you there what's in included in the beta's. Therebye they don't tell you how to use everything (some things they do). This because of the beta-thing of course. But then it's quite nice to explore question and found out new options every now and then..
