[galaxy-dev] possible bug - user log in / browser cache

I have a local instance running. When I'm logged in as user1, log out, then try to log in as user2, I keep getting the "You have been logged out" message. Its as if the browser's cache is retaining some information. To get around this, after I log out as user1, I have to click on Analyze Data, then click on Log in to log in as user2. I'm running Safari on Mac, but have noticed this with Firefox as well.
