Sorry about the signature (I have WIN & MAC) but just using MAC these days smile (Now adjusted)

So...
I scored a song Verse 1, Verse 2, Chorus, Verse 3, Chorus, Chorus, Tag end (60 bars)
Stepped through (TAB) in notation entering the Lyrics for V1, V2, Chorus, V3,
Tried to copy special Lyrics only to next chorus. Result was removal of all Lyrics (opened my back up) tried again same result.
When I then attempted to the step though and add the 2nd chorus manually, I found words missing in earlier work, thought it was my mistake so corrected.
As I corrected and continued to add Lyrics and play song & check all seemed OK until I closed & reopened, Lyrics then moved around with no logical pattern. The which I know I corrected changed to another word from with in the song.
Re-did this several times over several days making revision copies as I went. No luck.
On several occasions rather than correcting with the "L" tool I stepped through and edited with the "E" edit box deleting & Editing text in the edit dialogue window.
All fine until I reopened then Lyrics all over the shop.

I have over 100 finished songs which I have scored with Lyrics (most in WIN but some in MAC) so I'm used to the usually glitches you get along the way (WIN is easier for Lyrics as you can slide the but not perfect)
However, this is really weird (Maybe a corrupt file)??
