Formatting changes reverting
I click format, style, lyrics, and then increase the min. gap between syllables. The changes appear on the score. I exit out of the pop-up, and everything reverts to how it was. I do not see any button indicating how to save these changes.

The OK button is at the lower right corner of that dialog. If you don't see it, it's likely outside the display area, "below" the edge of your monitor. Press the Tab key repeatedly until the four buttons at the very bottom of the screen appear: Reset all styles to default (at left), and OK, Cancel, and Apply to all parts (at right).
