I have Contribute 3. I edited a page, published it, and later tried to
rollback to an earlier version. I got an error message saying that I couldn't
rollback a page that I was editing, that I had to cancel or publish the page in
order to rollback. But I had already published the page. I got the same error
when I closed Contribute and went back in to try to rollback. It looks like I
am not able to rollback at all. I have been able to rollback in the past.
