I have a page with several links, and clicking some of them will open up a WebDialogWindow which contains an iFrame.

However, if I click link "a", closed the WebDialogWindow, then click link "b", I initially see the ASPX page that was the result from clikcing link "a", until the ASPX page that should be displayed after clicking link "b" takes over, i.e. when the browser received HTML to display.

Is there a way to set the ContentUrl of the ContentPane back to "about:blank" (or another URL) when the user closes the WebDialogWindow? This probably needs to be done on the client side.
