\o/ Yay for stoffe! Did you answer your own question then? The *4 part seems like it should be there to me too... but then again I'm not a C++ guru. I would've expected the use of brackets here to denote element iteration. (Don't like having to think at this level with my programming either, stoffe.) I remember this is the area I fumbled through with trial and error also until I got something recognizable.
