Hi! I applied Matt's http://orgmode.org/worg/org-hacks.html#sec-1-7-1 to preserve top level headings when archiving to a file.
However, when I do archive headings, I get a "ad-handle-definition: `org-archive-subtree' got redefined" warning which I have to look at a couple of seconds before it finishes. How can I prevent this from blocking my time? Thanks!
