[ESS] no output in ESS until interrupt

[Ross Boylan]

While debugging an R function I noticed that the main *R* window did not 
show any output after an error occurred, until I hit ^G.  This was true 
even when the output was from the recover() function.  ESS may not have 
shown the output of a regular, but slow, function either, even if there 
was no error.

Are things supposed to work that way?  Anything I can do about it? I 
don't recall this problem in the past, but that may be because I wasn't 
using long-running functions.

ESS 12.04-4 [rev 4896], R 2.15.0, emacs 24.1.1 on MS Windows 7.

Thanks.
