Now that's a good one - it's the first hit in google and it has been  
discussed in the archives for many times and is really hard to miss.  
But I guess it's not surprising given that you also missed
"Updated R GUI (revision 4944) for R 2.6.0, 2.6.1 and 2.6.2. It is a  
bugfix update to the R GUI supplied with R 2.6.2, most importantly  
fixing a problem where hitting <ESC> has lead to an infinite loop."
on the CRAN download page posted just 5 days after the release you're  
using.

The current release version of R is 2.7.0, so you're using an old  
version and we ask you explicitly to not report problems on  old  
versions, again you failed to read that as well ...
