Although I can use the vertical scroll bar, my page UP and page DN buttons are not behaving. When I press and hold to get to the bottom or top, the screen just jitters and goes nowhere. I can press/release for individual steps to move and in other programs it works as expected. Could there be too many entries on a page that makes this fail? I see it in my list of assignments too.
I doubt that this happened earlier during this semester.
Thoughts?
