*sigh* if you only would read the whole thing. Your solution will still 
not tell me where the decoration really is so i can't avoid it. And how 
would i decide about whether i have "plenty of place on the left side" if 
i don't know what the dialogue frame size will be. Secondly your proposal 
won't allow me to place the dialogue next to my document if possible. 
Besides resizing the dialogue is not really an option, it will have a 
minimum size.
