Hi Ian, I have been trying to create a solution very similar to your channel 9 linkst that open in a content viewer window. I can see that you are appending the URL with the Channel 9 url and that is being loaded by the Media Player. I would like to be able to list a number of MindMapper documents and then feed the URL of the document into another web part page that contains the MindMapper viewer; the URL of the MindMapper is inserted into the object tag and the file clicked displays in the viewer. Any thoughts? Many thanks and keep up the excellent work on the site and blog, I read every post. Cheers Ben
