Criteria area is hidden on choosing "deselect" twice.

Criteria area is hidden on choosing "deselect" twice.

I'm using MSIE8 on Windows 7 64-bit.
 
Steps:
  • Navigate to the user input scripting section of a field.
  • Make sure Script Builder is displayed.
  • Drag "deselect" over.
  • Select the "DeSelect All" option.
  • Select a field, obviously.
  • Click "Done".
  • Drag "deselect" over again.
Bug:

The "DeSelect" option is selected by default, which is fine.  However, the criteria area is hidden.

 
Selecting "DeSelect All" then "DeSelect" redisplays it.  But, a bug is a bug, you know.
 
MSIE8 is apparently fundamentally incapable of closing the attachment window, so here's a link to the screenshot:
