I know that there was a change in where the scroll bar 'bottomed out' during one of the betas. As long as it was reasonably close to the bottom of the scroll bar I suppose that is acceptible, but it is definitely going to raise questions.
Tonight after downloading Beta 9 I notice that one of my notes stops about half-way down the scroll bar.

I cannot scroll past this point. I don't actually recall whether there is anytihng in this note file beyond where the screen clip shows. It is disconcerting to not be sure.
Here is a clip from another note file with what I considered was more 'normal' behavior:

The scroll button is near but not at the end of the scroll bar on this one. This is in Beta 9 also. So do I have a note file anomaly or will other note files scroll like the first example?
