I don't recall any previous behavior of dragging up or down turning a full page - it always moved the amount you drag it, just like any normal website or pdf would behave on a touch screen. If my memory serves correctly, previously a full page turn in vertical scrolling mode was only triggered by tapping on the left or right side or swiping left or right. Never up or down - this is a big problem for me.

I don't have my tablet with me right now, but I did not notice any pattern of when this occurs - seems to be most times I try to adjust the page, usually about the time I've moved about 1/2 to 3/4 page. 

Normally I'm doing this during short rests to because the original music was written in a 2-page format and I need to see staggered across the page turn. When it jumps, I have to go back and find where I was on the previous page.
