Problem: After upgrading to the latest version of BookWhere or MARC Notepad, the SendTo Mandarin M3 option has disappeared.

M3 does not register itself properly with recent versions of BookWhere. In order to correct this problem, you will have to download and run this M3/MARC Notepad patch. Another problem is that M3 does successfully unregistered itself with BookWhere so this patch has been designed to set the Read-Only status on the SendTo.xml file which is created to prevent the patch from being removed with each run/shutdown of M3.
