Hmm, thanks for the report.
Unfortunately I (and others) have repeatedly found that the
 text <-> code   mode switching for editing Rnw files, has
sometimes been behaving "illogically" / "stubornly" / ....

I have never started trying to find out how to fix it.
If you (or anyone in ESS-core {which is listening to ESS-bugs})
have time  or know of someone else (smart in Emacs & Emacs lisp)
who'd have, we'd be very glad for helping hands...

Ok, that sounds like something that is fixable before release.

Thanks a lot, Markus!
