I don't think the behavior he is describing is normal.  It's not that it
jumps a lot, rather it jumps twice.  Two distinct page-downs.  When this
behavior is found in MVC, it is also in Morphic- at least where it occurs
for me on WinCE 3. This behavior does not exist on Mac OS X.  This lack of
consistency hints to me that it's not normal, but some difference in
handling events.
