IF you change the STYLE on F5,
it CORRUPTS ALL THE OTHER STYLES IN THE SONG!!!!!!
And you cant / back delete out of it.
I have BIAB 2019, and this is working for me. The below link is to an AVI file showing BIAB playing a chord sheet where I've changed the styles at bars 9, 17 and 25 (this is shown as a red line under the bar numbers).
Test file - video of chordsheet including style changes (link)Every thing runs smoothly.
To delete any of those style changes, I simply place the cursor on the bar where the style change occurred (i.e. bar 9, 17 or 25), open bar settings (F5) and then press "Clear Style" as shown by #1 on the top image below.
If I want to get a summary of where the style changes are, I press "Print Summary" (#2 on the top image below).
When I pressed "Print Summary", BIAB gave me the summary of style changes shown by the lower image.
