Which method are you using to store the text into the RichEdit?  Are you
using setText(), or are you using appendText()?  appendText() will append
the text to the RichEdit, and shouldn't make anything dis-appear.  setText()
is basically clearing everything in the RichEdit, and storing the new text
in it, as a clean sheet basically.

One thing I would suggest to you though, is to check and see which version
of RichEdit Win32lib is linking to, and weither or not, you have 2 versions
of RichEdit installed on your computer.  Cause some of these problems sound
as though something I encountered with RichEdit 1.0, which wasn't as
sophisticated as RichEdit 2.0 or 3.0 for that matter.  And some of the
RichEdit structures have been known to not work properly with RichEdit 1.0.

Just some things for you to check.  I'd check myself, but Unfortunatly, I'm
on Linux now, and don't deal much with Windows anymore.
