We are using 4.5.1 version of Telerik HTML editor.
While creating a hyperlink inside the editor it brings up the dialog box for selecting the link, but it doesn't creates any link in the editor.
Kindly request your thoughts on why this is not creating any link in the editor control.
Version 4.5.1 is also based on RadEditor Classic which development is stopped in 2009 and it does not support the modern browsers. The only suggestion that I could provide is to test the latest official build of the free RadEditor for MOSS 4.5.6 and see whether its link manager behaves better.
Currently, Telerik supports only RadEditor for SharePoint 2010 and RadEditor for SharePoint 2013, which are based on the latest version of RadEditor for ASP.NET AJAX Q1 2013.
Kind regards,
Rumen
