[R] [ESS] R window: Text is read only (: Another round :)

Dear All

Working along in R (Emacs {Aquamacs}, ESS ) usually I am getting a long 
R buffer with many rows. To reduce its length, I used to select 
backwards and delete those unnecessary rows. Now I cannot do that, only 
C-k allows single lines to be deleted. the mode line says 'Text is 
read-only *R*>'. Both R and ESS are up to date.

Aquamacs 3.3  GNU Emacs 25.1.1 (x86_64-apple-darwin14.1.0, NS 
appkit-1344.72 Version 10.10.2 (Build 14C109))

R version 3.4.3 (2017-11-30)
Platform: x86_64-apple-darwin15.6.0 (64-bit)
Running under: macOS High Sierra 10.13.2

ess: 0171204.1404

This behaviour exists at the very start of R where I cannot evendo 
anything in R.

The *ESS* buffer says

(inf-ess 3.0): prog=R, start-args=--no-readline  , echoes=t
Making Process...Buf *R*, :Proc R, :Prog R
  :Args= --no-readline
Start File=nil
(inferior-ess: waiting for process to start (before hook)
(inferior-ess 3): waiting for process after hook

What additional information could be helpful to stop this strange behaviour?

  TIA  C.
