Diagram frames without a frames?

[alexd]

Hi all

I have a lot of a small diagrams with parts of GUI (i mean some custom reusable user objects). I need to put these little diagrams on the "dialog box" or "screen". Using drag and drop and select the "Diagram frame" provide almost real dialogue, but there very abolishes borders around diagrams. How can I disable these borders?  [smiley=undecided.gif]
