I avoided the notation entry feature in BiaB for a long while, mainly using MuseScore for composition of melody. I spent some time on the BiaB notation view because I wanted to have all the elements in one piece of software. So I got used to this entry method on the Melody track and found it reasonably good.

I've just tried to enter notes the same on the Soloist track and this has been a disaster. I found that often the notes don't entry properly but, worst still, also that Ctrl Z does not reverse the most recent entry and nor dose selecting undo from the edit menu. If I switch back to the melody track then all works as specified in the manual.

I have updated to the latest version but no change.

Any ideas please?
