Hi, please fix login issue, QL login doesn't work right if you press f5 in a browser.

This is actually annoying thing guys, sometimes servers don't refresh info and i press f5 to refresh entire QL page, then i getting this: "An instance of Quake Live is already running. Please close this web page." and can't login/logout/refresh page for about 10 minutes or more. it supposed to refresh QL page instead of got me logged out without ability to log in quickly...
