Boy... I feel like all I am doing today is finding little bugs. Sorry for all these reports right in a row...
When I create a highlight/note and attempt to change the note, I occasionally am not able to select items at the bottom of my highlighting palate. The context box extends below my screen and I have to do some real finagling to select the very last highlight in the box. This happens particular if you are working on a note that is right between the spot where the box decides to display either above the note or below the note (so the note if located just below mid-screen). See the two screenshots below.
