On restoring any project's autosaved backup file, the movie tabs are reversed here. Particularly irritating on the project I was using, with 10 (low content) tabs. To get them back to my arranged order they would now need moving (one step at a time for each - tedious). A simple example was shown in the 6th screenshot of my post in the parallel HDR thread.
Anyone reproduce please? I suggest setting autosave period to 1 minute for a quick test.
And that suggests a possible work-around in cases like my 10-tab example: after discovering the reversal, wait for another autosave, which should reverse the reversal.
