Could you please, tell us whether you are using RadEditor Classic
(RadEditor.Net2.dll) or RadEditor for ASP.NET AJAX
(Telerik.Web.UI.dll)? If you are using RadEditor for ASP.NET AJAX just download the latest version from your Client.Net account (Purchases and Downloads) section and upgrade to it.
If you are using RadEditor Classic, please open a support ticket and I will send you the developer build of the hotfix.
