When I "Unfold to 1 BIG Chorus" and/or try to resize BB app window, the song sheet won't scroll down (i.e. the scroll bar moves, but the chord sheet data doesn't).

Work around:
Save the file after you've Unford it.
Close BB.
Start up BB with the saved file.
Should function as normal.

However, I can't seem to get around the resizing of the window issue.
