I'm having a bit of a problem with a TreeView embedded in a TextView which
is inside a ScrolledWindow. I've attached a little program that exhibits
the problem: the TreeView doesn't always redraw correctly when scrolling
down, and then back up---sometimes the border disappears, sometimes the
lines aren't redrawn, and sometimes users get gray areas, like this:

I'm I doing something wrong? Is there a better way to mix text and a
TreeView widget? Or, is this a bug?
Thanks for any pointers,
-Doug
