Whenever a page element is expanded, so that the screen content becomes longer, the LimeSurvey footer bar is not redrawn at the bottom of the page, but rather stays in the same place, covering a part of the new content. This can happen in ANY part of the user interface where there are expandable elements, such as on the response or participant browsing pages, when a larger number of display items is selected (see attached screen capture), or on the Survey Settings page, when expanding any of the settings sections on the right side.

This only happens on the Chrome browser. Firefox is fine.
