Rich:
    Both IE and Firefox are unable to find the link you supplied.  However,
that's only because I've restarted my R session since I pasted the error
output (and it appears that each time I restart R, the URL is slightly
different).  This time, I get:

> ?sum
starting httpd help server ... done
Error in shell.exec(url) :
  access to 'http://127.0.0.1:31836/library/base/html/sum.html' denied
 ---
If I paste the new URL into either browser, I can read the entry without
issue.  This is what I've been doing to read help entries, but it's tedious
to copy and paste the URL into a browser every time I want to read the entry
for a particular function..

Happy to hear any other ideas!

Best,
Jonathan
