I observed that scrolling was noticeable slower when the handle for the
field content contained a large amount (>32K) of data.  In an attempt to
figure out whether it was my use of fields that caused the slow down or not,
I hacked the database (I'm putting database record handles in the field) to
put a NULL terminator in the middle of the text.

The result was a visible increase in scroll speed - an increase which got
bigger the closer that NULL was placed to the current scroll position.  This
seems to imply that the word-wrapping algorithm for fields always scans to
the null-terminator.

If this is correct, is it really necessary to do that, i.e., is there some
hope that Palm will improve this?  If this isn't correct, what am I missing,
and is there something I can do to improve scroll performance?
