It appears that D7 B5 may be done tonight, and I have done a clean install of b4, plus all of trac's updates up to changeset 12400 and I cannot logout as the admin.
When I logout, I get redirected back to the same page, but stay logged in. Also, the bottom bar has mysteriously dissapeared and I do have the grey icon after attempting to logout, so i'm not sure if it's related. Not sure if it's a partial logout, but I can still do everything as though logged in.
i am running this in a subfolder this time, using FF on a vista machine.
So perhaps before b5 is released, the logout problem could be checked.
thank
