I did a mailmerge, and then the next time I opened that document, it was
attached to the data I had used in the first mailmerge.

I didn't mean for the connection to persist - I guess I saved it wrong,  I
needed to save it, because I made some changes to the text.  Maybe I should
have saved the document before beginning the merge, but I didn't.

Is there any way to unmerge the document?  I have some complex macros in the
document, and I don't want to have to mess with them.
