the Jx.Dialog class has an 'Action' area that is used for buttons.   
Unfortunately this was poorly thought out (at least for more generic  
use) and so it is difficult to not have this action area.  I believe  
you can get rid of it using CSS (set its height to 0).  We are  
reworking the Jx library to use mootools instead of scriptaculous/ 
prototype and this is one of the things that I want to clean up.

Are you referring to the fact that there are 2 divs of id Loading?   
Somehow that code is getting called twice - you will need to set a  
breakpoint on that line and confirm what is happening, but I suspect  
that you have two instances of your widget or two wigdets that use  
blockui.

Jx.Dialog tries to manage the z-indexes of dialogs to keep them in an  
appropriate order, I believe.
