Very difficult to click/drag corner handles to resize crop/ken burns
I'm using FCPX 10.1.4 on a Macbook Pro Retina 15 (mid-2012), Yosemite 10.10.2. However, I've seen this problem over the previous several releases of FCPX, and also in OSX 10.9.x
When using the Crop/Ken Burns editor, the corners of the area are bracketed with blue handles (or red/green for the ken burns edit).
Here's how it's supposed to work, as I understand it:
To move the crop region, you click within the bracketed area and drag to move the crop-window over the source material.
To resize the crop region, you click a corner bracket handle, and see the bracket change to a slightly larger bracket, then drag it in/out to make the area smaller/larger.
However, I find that most of the time, when I try to click/drag one of the corner handles to resize the area, it instead acts as a move operation.
Even worse with the ken burns editor, often the click toggles between the start and end crop regions, when I really wanted to just resize one of the regions.
In short, I find these brackets unbelievably fidgety to click/drag for resizing/cropping. It almost always doesn't work right, so I find myself wasting a lot of time with click/drag/undo, try again, click/drag/undo, try again, etc, until finally the click works as the intended resize.
I've tried everything I can think of- modifier keys while clicking, click and hold a moment, double-click, etc.
Is this a bug, or am missing something?
Thanks,
John
