Oh, those random 2/4 bars in folk music, gotta love 'em.

I haven't tried this, but save your work and try this on a copy of your song: go to where the 2/4 measure would be, press F5 and change the beats per bar value to 2 (it probably says 0, the default that normally means 4). Then go to the next measure and press F5, and put in a 4 to restore the rest of the song to 4/4.

If that doesn't work, or if it messes up the melody placement, it is possible in the Melody menu to timeshift the melody. Write back if you need more info on that.

As for the drum fills, it sounds like you already know about A & B, blue and green part markers, by left clicking on the measure numbers. I don't think there is any other way to control the drum fills. If you meant something else, please explain.
