I'm using Version 2023 (1013).
Here is what I did in more detail, nothing fancy. My goal was to compose a jazzy version of Feliz Navidad for my local jazz group's Christmas party. So I hit File New and started from scratch. I first entered the chords into the Notation window, 48 bars with intro and ending. I then clicked "Notation" to get the window that has the treble and bass parts with the chors on top. At this point I clicked the small icon two to the right of the Print button and that shows vertical lines where you can click and it makes a note at the spot where you clck. I then entered notes in all 48 bars, doing a File Save every 4 bars just in case. A couple of times I made a mistake and went back to correct it by retuening to the notation chord window, clicking on the bar I wanted to see, then returning to the bar I wanted to change. It was all there with notes and tabs because I have tabs on. I also played the chords I had entered several times just to check and it played through. I did all 48 bars this way then did a final Final Save Song. At this point I don't recall but I think I opened another song and then closed it and openned the one I made. It shoudn't matter becuase I had saved the song I was working on multiple times. The last time I opened it all I got was the original chord sheet, no notes, no tabs. That's it.

The window is still open but I have no time to redo it now. I have to perform this soon so I'm just going to a capella the song by guitar only and just jam around some chords. Too bad, I really wanted to use BIAB for a nice latin backing track.
