Dear Elaine

Thank you for the promt reply and the detailed suggestions.
The semicolon separator is a nice hint, I will use that a lot from now on and that fixed my hbonds issue.

I used the setattr p labelColor 0.9,0.9,0.0,0.0 suggestion to deal with the labels, thanks for that trick. I did not try to move the labels, undisplaying them at some point is good enough for me.

And lastly I am now using windowsize to get rid of edges, had to adjust the script a little bit when stuff didnt fit anymore, but it worked out well. I normally use "focus" to get to a nice centered position but I will consider the savepos in the future.

Thanks again, best wishes
Matthias
