Hello again
I'm having some problems running some examples with version 0.9.8.1. For
example, rbreu_fc.py and rbreu_scrollbar.py.
It seems that some stuff has changed in urwid since I last tried my examples.
I'm very busy right now, I can't fix it until next week. :(
This patch fixes the crash due to canvas changes, but the scrollbar
seems to be stuck to the top now.. I'll have to keep looking to see
what causes that.
