Dear Paul:
Thanks for your prompt reply.
The full error message is as follows. Text in < > is comment from me.
------------------------------------------------
Run-time error '4605':

The

Continue <Greyed-out button> End Debug Help
--------------------------------------------------
This error occurs independent of where the focus (cursor) is. It happens at the beginning, in the middle and at the end of text, or in a new blank document.
I do not use headers or footers in documents. However, when I create a header and put the cursor in the header the error message runs:

------------------------------------------------
Run-time error '4605':

This method or property is not available because the object refers to a header or footer.

Continue <Greyed-out button> End Debug Help
--------------------------------------------------
So being in a header does make a difference.
