My ASP.net web page has an Overview displayed in a split pane (telerik) and when I change the panel size or collapse it, the control moves (or disappears) properly but the highlighted "view box" remains behind. Is there a method or technique to get the control to update the view box location to the new control location.

Also, when I resize the associated ViewDiagram, the Overview generates a new "view box" without erasing the old one. I suspect that these issues are related.

I appreciate any light you can shed on this problem.

Thanks much!  The updated version seems to work much better!
