We use the RadEditor in our application and we always display it in design mode, unless the user has read only access, in which case we display it in preview mode. The reason for this is so that they can edit right away without having to switch back and forth between modes. We have a problem with hyperlinks. In firefox, you can ctrl+click on a hyperlink in design mode and the hyperlink will open in whatever target you've set up. In IE, it just selects the word. I'm trying to work around this by implementing a custom tool on the context menu of anchor elements. I've figured out how to add the tool to the context menu and how to set up the handler... what I have not been able to figure out is how to access the underlying UI element (i.e. the context), which in this case is the anchor element, so that I can get the URL and open it.
