homas Rajiv had a user, <A HREF="http://host.notesboy.com/notesboy.nsf/dx/error-operation-stopped-at-your-request-mail.box.htm">recently upgraded to Notes 8.02</A>, getting this error every time he tried to send a memo. Uninstalling and re-installing the client would work for a day or two, but the error kept returning. He provides both temporary and permanent solutions on his blog.
