I am using a clean install of version 07.00.00 (1586) and cannot get the hyperlink properties to work in the html editor.  When clicking on the link manager icon or right clicking a link and selecting properties, I get the following error in the popup dialog:

Server Error in '/' Application.

I cannot find any evidence of other hitting this same error so perhaps it is my environment.  However, all else seems to be working flawlessly.

Looks like a bug in this version, take a look at http://support.dotnetnuke.com/issue/V...

I'm not sure our situation has originated from the exact scenario, however, deleting some files on 'DesktopModules\Admin\RadEditorProvider\Dialogs' helped me to solve that issue, just delete 'DocumentManager.ascx' and 'LinkManager.ascx'.
