RE: TextView and ScrolledWindow not behaving properly

["Jeremy Wise" <jwise springthrough com>]

I've noticed exactly the same behavior in GnomeICU when I add a message
to the text box.  For some reason, it's expanding the size of the entire
window instead of wrapping the word to the next line.  This gives a
pretty bad appearance... I don't know if it's a bug in the TextView or a
bug in the scrolled window.. also, a TreeView in a scrolled window can't
be shrunk below the width required for the longest string in the view.

Later,
