My apologies, duplicate, please delete, first time using bug reporting.
The dropdown menus e.g. Notifications, User Control Panel, Subscribe topic (version 3.2) do not work correctly in some mobile versions of Safari. The problems have been found on some Ipads and iPhones probably running older versions of Safari, not on the PC version.
The dropdowns once open do not disapear as you navigate away, multiple dropdowns can be opended onscruring the text on small screens. One of my users reports that he can close them (three dialogue boxes open) one at a time but each reappears when I close the next one. This is very odd behaviour!
