[R-SIG-Mac] Blank help window

Thanks for your persistence and kind help.

(1)  Comparing output of options()

R.app options() includes 

[1] "html"

that terminal R options() does not.  Here's the diff of the two...

> "http://cran.utstat.utoronto.ca" 
< [1] 80
> [1] 168

(2) Removing ~/Library/Preferences/org.R-project.R.plist

Starting R.app after removing the plist does not resolve the blank help window (but did restore R.app's factory-default appearance and settings.)

> help("help")				# brings up blank help page
starting httpd help server ... done
