At the home screen of the SEP 12.1 Small Business Edition Management GUI, there is a portal window for Virus Risk and Activity Summary.  Inside of this windows, there is a drop down for the time window you wish to see the activity for.  It does not work as expected. 

When you hot the dropdown arrow, it drops a menu with preselected time frames.  You cannot select one, as it appears "unjoined"  to the drop down screen.  When you move the mouse off of the drop down arrow, the selection screen disappears.

You can see under the words Cleaned / Blocked is the drop down menu.  You are not able to select anything once you move the mouse cursor off of the arrow to the right of the "Last 7 Days"
