	/* Update LOG 
	
	January, 28th - Fixed problem when double clicking on a pane(i.e. expanding and collapsing).
	1/2/2008 - PKB - There is a problem with this script pathing for images. You must specify the graphics page from the root of the server for this instance. This should be adjusted to be dynamic at another time.
