Hi,
When I want to crop in full screen mode I can call the option with a short cut key and the screen edges show points where I can grab the crop frame for resizing.
The problem is with the top miniature bar that comes down as soon as I try to grab one of the three points on the top crop line and it will not go down until the crop function is closed.

Is it possible to stop this miniature bar from appearing during a crop operation?
