Argh, I am post-reply-reply'ing again :)

I found the entry-widget in window->preview at balsa-message.c

Remove the patch against main-window.c and patch balsa-message.c :)

So.. the scrollbar will have to move "up" when (y < 9) and
down when (y > (widgetheight-9)) .. remaining questions :
How to get the widgetheight (item in balsa-message.c) and
how to move the scrollbar up/down.
