Can you file this in http://bugs.modx.com ?
Done - the non scrolling bit.
I did look at the html/css for both things I mentioned a bit... - a bit complicated, perhaps overly so? I did not see any quick fix to hack for myself.
and the Save, Duplicate, etc buttons - they use tables for layout !?! - yep each button is multiple columns and rows as is the space between them, I was expecting the usual menu style i.e. a list with anchors styled with padding/margins/floats and so on - lets just say it is not a technique that I will copy!
And so I aim for the center of the buttons, improve my mousing skills and watch for the success pop up!
And when I think first I just use Opera!
