Always most thankful for your willingness and replies.
So - I have deleted these markings (+1 stave -2 staffes) as you have suggested, this have resulted in terrible chos as all the music was erased leaving aside but a few surviving notes spreading here and there wondering about…
I have realised that Dorico doesn’t agree with my measures as of 48 so I have decided to erase everything as of that measure, this have created obscurity onto measure 47 which I was able to fix fast enough.
I have then acted as instructed, alt click to place the about to be pasted material ctrl+c and ctrl+v, the result came with stemless notes missing notes
and total chaos.
I have then started to copy notes from a backed up project to the “new” one but for no avail, I have worked with one measure trying to copy and paste small segments but that didn’t work either as Dorico gave me rests in return for the notes copied in.
As I am on a trial basis, my conclusion at this point is that although it was very easy to be embraced by Dorico in the beginning and work with it, the problems I am getting will prevent me from purchasing the software either because what I do is wrong or for whatever other reasons.
I think I should return to the pencil and his friend the page to deal with all that and leave this work ro a pro.
Most kind regards - cheers - Rami.
