Start ez (at the default size of 500x500) with the file:

/afs/athena.mit.edu/user/w/wdc/ezbug/arrow_scroll

And use the down arrow key to scroll down through the file.  When you
get near the bottom of the file, scrolling stops happening.

My guess is that there is some point when the scroll computation gets
confused near the bottom of a file.
It may be the amount of the file on-screen.
It may be the page break.
