Xbae Matrix Widget Question

[GAIL CRAWFORD]

Really enjoyed playing around with the Xbae Matrix Widget. I have one question: Is there an easy way, after a resize, to adjust the width of the last column to fill-out its width to the widget's size (fill resource is true)? When I do this, the color beyond the last column uses the core background color, and I want it to show the existing row color(s). Thanks, David Crawford
