I am using MiKTeX 2.2 under Win2000 SP3
any document with Yap 0.99a in single/double/continuous view
and using <END> to go to the end of the page.
I expected the
lower end of the page at the lower border of the window.
<END> shifts the lower end of the page up to the upper border of
the window, which is filled with grey background.
