Hi,
In the current master -- "Git revision: 0954bfb from master branch,
committed on Jun 16, 2012 at 01:02 AM by Marc Delisle", I see the
character 1 at the top of both the navigation frame, near the top of
the main frame, and also at the bottom of the main frame.
I'm away from my main system at the moment, so I'm afraid I can't
'git-bisect' to the problem commit, sorry.
Regards
