Right, I'm using the ess Debian sid (upstream SVN) package that Dirk
Eddelbuettel kindly provides. Haven't yet used Rnw-mode with this
version, but the <delete> key issue is certainly not catastrophic! :-)
One can just do the standard 'C-d' to delete forward in the meantime.

Maybe you mean the thread I followed up to?

The problem is also there with the released GNU Emacs 22.2.1
(x86_64-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of 2008-11-09 on
excelsior, modified by Debian.
I'll try to track this down in the source when I have a chance, so any
pointers as to where to look would help.
