When using Internet Explorer 9, up/down text box arrows display to the right of each entry displaying on a page employing the "Content by Label" macro.

We think we may have identified the root cause.

It appears the "LI" element in the CSS for the Content by Label macro is set to "overflow: auto".

When "auto" (overflow) is turned off, the text box up/down arrows do not display. This setting is configured in the file "content_by_label_resources.css".
