Final Cut Pro [NAME] playhead jumps when adjusting start/end points
I'm using the very latest version (12.3) of "Final Cut Pro" which is running on a 4TB MiniMac using the latest version of Tahoe 12.6.2. The issue concerns the "Ken Burns" feature of the cropping tool: with the playhead on the selected image, and the "Ken Burns" option selected, EVERY TIME I touch either the "Start", or "End" windows, the playhead jumps to either the 'beginning' transition, or the 'ending' transition in the video timeline, resulting in a view of the overlapping images making editing virtually impossible.
How can the playhead's transition jumping be disabled so that it STAYS on the selected image without jumping when the Ken Burns features are being used?
