Hi!
Several people already confirmed to me, that their stackbuilder does not work properly. Which button ever you choose for a project ('Yes, I use it' or 'No, I don't use it'), the status-indicator occurs and stays there endlessly. A reload of the page after several minutes shows that the desired operation did not take effect.
For debugging: I'm on "Mozilla/5.0 (X11; U; Linux i686; en; rv:1.8.1.12) Gecko/20080211 Firefox/2.0.0.12" on a Gentoo Linux.
TIA for looking into this! Cheers! Toby
