Thanks, Robert. Yes, I was kind of thinking along those lines as a justification for Bing to be adding these into the list of errors. I added the robots meta tag because, like Sand said, I could not see why I would allow cached pages of my site to exist anywhere beyond my control. Besides, many are dynamic pages that make no technical sense to be cached anyhow. So, I guess I should chuck that up to BWT weirdness rather than a general SEO issue.
