Not possible to delete an instance of appointments in recurring series created with C++ API

I have an application that creates meetings via the C++ API

If I create a repeated meeting in Lotus Notes 6 (StdR6MailTemplate) via the C++ API and then delete an instance of the meeting the whole recurring series is deleted.

In the client is shown something which appears to be a correct series but if you try to open an appointment LN will show the error message:

“Error trying to open document: Invalid or nonexisting parent document”. Editing one or several instances of the meeting works fine.

The fault occurrs with Lotus Notes 6 and 6.5 only - it works for Lotus Notes 5.

The error does not occurr if I omit to set $CSVersion - however not setting this causes other problems…

Any help would be highly appreciated.
