After I installed it the font issue disappeared, I can now see the chords in the notation window display properly.

Also, the delay for there black bars to move when starting a song is gone. I think "W"s tip to regenerate also made a difference. I didn't do that the first time I played the tune after opening BIAB, but the display worked okay. Then I hit "regenerate" and it still played okay but the tracks were somehow much improved from the initial version.

I installed the last available update (106) but the song form still won't allow me to create a C section, I can only create A and B sections but no C section.
