I can only get this to happen in chrome. My version is 10.0.648.205 If you pick the Quick Navigator from the main forum all is well. If you move to a sub forum or thread it causes the page to jump up. http://xenforo.com/community/forums/add-on-releases.32/ + User the Quick Navigator. http://xenforo.com/community/threads/backward-compatability-breaks.13290/ + User the Quick Navigator. Funny enough the home page doesn't do this.. Any one else finding this.
