hi peter i'll look into this bug shortly i will run a trace of your classifications and see if indeed some of the revisions do show up twice this is pretty core functionality for something to go wrong and unnoticed for so long although maybe it is specific to the wikitrust queue which does not see a lot of use this is the user name you were using and you logged in with the same user name both times right can you describe what the scrolling issue is i fret this could be a tougher fix its not like i actually implement scrolling this is just something java provides also you'll generally find that the accuracy of classifications among the queues looks like cluebot ng stiki wikitrust assuming everything is working correctly this is of course is dependent on a complex set of criteria how many people have been using a particular queue lately etc thanks
