In the frame editor, if I go into split-screen mode by dragging the split box/bar then it works fine. However, if I then try and change the zoom level for one of the screens then it messes up: It changes the zoom level for both windows but only updates the scrollbars for the currently selected window.

I'd prefer it allowed for different zoom levels as in the event editor, but if not then removing the scrollbar bug would suffice.

Note: I've tried it on build 246 and 247 (HWA Demo).
