On v7.04.4, I'm finding that a Replace edit does "not respect" the instance of ADD-Edits on Timeline Clips. In the past, I remember a Replace ending at an Add-Edit point. however all is not lost:
When I remove Marks from Composer, Replace DOES respect ADD-Edits and works as expected.
I just don't recall MC's Replace as deferring to Marks, and in effect, doing and OVERWRITE while pressing REPLACE key.
