When logging out from gnome, the "Yes" option in the logout box is
selected, but it's the "Help" button that has the default.
This caused a lot of confusion for me the first time, as I was presented
with a help window instead of the usual logout when pressing Enter in that
box.

This bug is present in most versions of gnome 1.2 - I saw it the first time
on Helix and reported it as a bug there. No response yet, as with many
other Helix bugs.
But it would probably be nice if the new Red Hat didn't have this bug, and
maybe the original gnome source was patched too.
