Hello,

I just updated to R 3.4.1 [R.app GUI 1.70 (7375) x86_64-apple-darwin15.6.0] 
from http://mirror.its.dal.ca/cran/ but have encountered a puzzler.  When I 
lunch the help viewer like this...

?data.frame 

the viewer launches but the page content is blank.  I have also tried he search 
box in the help viewer as well as the menu selection 'Help > R Help' with the 
same result.  I have restarted both R.app and the computer without joy. The 
startup message and output of sessionInfo() are pasted in below.

I can get help successfully from a R session in Terminal.app.  I poked around 
in the list archives but don't see anything recent on this issue.  

What should I do to enable the help viewer?

Thanks!
Ben
