OK
When the dialog is opened it displays and aspx page that has some <asp:LinkButton> tags on. These tags post the page back to the server in a normal browser window but in a dialog box they open another window with the url "BLOCKED SCRIPT__doPostBack('ctl00','\1')"
How do i make the page post back to it's self?
Cheers
