Sumit: I examined and tested the provided files and was unable to reproduce the problem which leads me to believe that you are using an older version of RadEditor for SharePoint. My recommendation is to upgrade to the latest RadEditorSharePoint.dll v.6.1.5 (Q1 2010 SP2) one where the problem should not exist.
Suthep: I cannot provide a firm estimate when the requested feature will be implemented.
You can obtain the source code of RadEditor for MOSS only if you open an official support ticket from your account and request it. You cannot open currently a support ticket because your support has expired on 25th
of March 2010. We will make an exception for you this time and send you the source code via e-mail. Please, send your request to firstname.lastname@example.org.
