Scrollbars Broken in latest visual editor

[WhirledPress]

Not only is the mouse disabled from scrolling using its scroll wheels, but the scroll bars on the side of the screen also are disabled except for the thumbs. You can drag the thumbs to scroll the content, but you can't click the arrows or scroll with the mouse. Rather clicking the arrows shows the clicked state of the arrow icons, but nothing scrolls.

Also, from within a block, a new set of full-screen scrollbars appears inside the outermost scrollbars (which make no sense and do nothing--mostly because the box is 1 unit high and doesn't need to stroll)
