Rounded corners problems

I am trying to do rounded corners on elements that are in a LayoutContainer (like the demo LayoutContainer)  Are there any limitations to the rounded corners (dojo.lfx) code?  It seems to add rounded corners to the top of most of the elements, but the borders don't get moved properly (so they don't line up with the rounded corners) and the bottoms of the rounded corners don't appear.  This is how I am applying them:

    var settings = new Object();
    settings.autoPad = false;
    dojo.lfx.rounded( settings, [ "middleButtonArea", "footer", dojo.widget.byId( "centerArea" ).domNode ] );

middleButtonArea is a standard div put in the top of the layoutContainer, footer is a standard div at the bottom, and centerArea is the dojo ContentPane put in with layoutAlign="client"

Thanks for any help or pointers,

Irv
