TOPIC: Control Panel - Front end - icons

Nathan,
not a bug, but trying to figure this out. I have my admin directory password protected on the server, so I have the DTregister control panel and other event management functions accessible on the front end with the correct authority level. But since I protected the directory I noticed that the control panel icons do not show, and I get a pop-up requesting the directory password. If it is not entered, everything appears to work, but no icons. Are the icons behind the admin "wall", or just being called by a routine that is there? Not a bug, but would be nice to have the icons be readable.

Latest Joomla and DTregister as of Saturday.
