Interaction Templates; Curser on the right position

Hello all,

we have an "Interaction Template" which opens a word-document for doing some notiz.

When open this word-document the Curser is always on the first position. I want that the Curser is on a defined position.

I tried to do it with a word-form. I put a textbox on this "defined" position and secured this document.
If I open this word-formular manually, the Curser is on the right position.
But if I open it by Navision (Interaction Templates), I get an error message:

The call to member OpenDataSource2000 failed. Microsoft Word returned the following message:
Die OpenDataCourse2000-Methode oder Egenschaft ist nicht verfügbar, weil das Objekt auf einen geschützten Dokumentbereich verweist.

in english this message should looks like this:

The call to member OpenDataSource2000 failed. Microsoft Word returned the following message:
The OpenDataCourse2000-Method or feature is not available, because the object refers to a protected document range.

How can I get the Curser on the right position on a word-document or word-form?

thanks a lot for future answers
