Locking Lyrics - feature request or broken?

[allknowing2012]

As I work thru the phrases and words I would like to lock them so that I dont inadvertantly "breakdown" the wrong thing and lose my work (recover from save blah blah blah). I can right click and lock the phrase, it turns red but it doesnt appear to lock it.
Is that the case or user error on my part?

I see now that it is locked - it just doesnt show it as being locked. Is it protected from any breakdown commands? I will try that...

I don't know I usually never lock anything.  It definitely did not look for locking when I first created the breakdown stuff but not sure if anyone else updated it.

This is not a bad idea. Locked word and phonemes should not be deletable.
