[ESS] C-c C-c in R console buffer causes Control key to get "stuck" (Windows)

[Mark Seeto]

Hi Rodney,

Thanks for your reply.

In Emacs 26.3 (where the problem happens), when I press C-h k C-c C-c
in an R console buffer I get the same thing whether I use left Control
or right Control:

-------------------------------------------------------------------
C-c C-c runs the command comint-interrupt-subjob (found in
inferior-ess-mode-map), which is an interactive compiled Lisp function
in ‘comint.el’.

It is bound to C-c C-c, <menu-bar> <signals> <break>.

(comint-interrupt-subjob)

Interrupt the current subjob.
-------------------------------------------------------------------

And sessionInfo() gives:

-------------------------------------------------------------------

I tried installing R 4.0.2 and the same problem happens with that R version.

I'll try looking at keyboard settings in Control Panel.

Thanks,
