The sort actually didn't change unless you have multiple files with the same date/time.  Prior to 118 and 119, files with the same date/time would sort randomly.  Now there is a subsort by file name but only among files with exactly the same date/time.

Can you give screen shot(s) or further details?  Both date sorts have been tested and are working fine on all my tests so I need specifics.

Thanks,
Mike

v120 got the thumb sort back to what I'd expect.

Thanks for the quick work.
