gmayor: still the same error when run on x.docx: Run-time error '5152.'" Same line highlighted in Debug as before: "oDoc.SaveAs2 strDocName." The macro opened a new document, but there's nothing in it. The debugger limits my navigation to see what's going on. But when I stop the debugger, the first chunk of text (i.e., text up to the first occurrence of .pa) does get added to the new doc. At that point, I see that the .pa delimiter has been removed from the source doc, but the initial text (i.e., that which has been copied to the new doc) is still in the source doc.

macropod: trying the revised SplitDocument macro on a fresh copy of x.docx, I get the same "Run-time error '4605.'" I get only an hourglass cursor at that point. I click Debug. As before, the "Copy" line is highlighted in the code. Not sure what you meant in saying that you didn't know what code line was highlighted. That's the only thing that seems to be highlighted. Nothing is highlighted in x.docx, as far as I can tell: I can't navigate while the debugger is open, and nothing is highlighted when I close it.
