"Replace selected clip" loses "Retime controls"

Hi All

Working on a proyect, replaced the clip I was working on with a better quality version, same clip, different extension (from m4v to MOV) and from lower case name to upper case name, and all the retime edits disappear

Any ideas? Is this so?

Thanks!

I think I recall another thread about this recently. See if a forum search turns up anything.

Thanks! will do
