silvertones & jford - Thanks for the quick replies.

As a programmer, I can say that the drawing surface of the window itself evidently has default maximum boundaries set. The window frame itself can be independently pulled/pushed/maximised but the frame's contents (the controls and graphics of the VST) will not expand past a certain internally set limit.

Hopefully Peter may soon respond to this.

@jford - The horns are nice and very usable!
