We deliberately removed the target="blank" attribute as it is not XHTML compliant.
Please refer to the following KB article to learn how to put it back (the provided example is for Link Manager dialog; for the Document Manager dialog you need to modify ~/Sitefinity/Admin/ControlTemplates/Libraries/Dialogs/DocumentEditorDialog.ascx file): How to extend the custom RadEditor dialogs
, you can always switch to HTML code view and add target="_blank"
to the anchor tag of your document.
Hope this helps.
