[ESS] ess-mode 5.3.6; ESS locks up with par(ask = TRUE) etc and C-c C-r

Dear list:

Consider the following code chunk in an ESS R buffer:

lm.SR <- lm(sr ~ pop15 + pop75 + dpi + ddpi, data = LifeCycleSavings)
plot(lm.SR)
summary(lm.SR)

If one highlights this region and does C-c C-r (to evaluate the region),
Emacs+ESS+R lock up completely and no matter what I cannot regain
control.

As it is not immediately obvious which functions are going to do this to
you, is there any way that ESS can work around the asking for user input
in the middle of a region commit?

Is there a key-combo that I am missing that would allow me to regain
control? At the moment I am resorting to killing R and Emacs as C-c C-c
and C-c C-z don't appear to do anything.

All the best,

G
