[R-SIG-Mac] Blank help window

[Simon Urbanek]

Few things to try:

- do you see anything in the error console?

- remove (rename) any and all customization files like ~/.Rprofle ~/.RData etc.

- try running R from the console and starting the html help by hand to see if it works at all:
tools::startDynamicHelp()
help.start(browser="/usr/bin/open")

- if that works try the same from the R.app gui *before* using help:
help.start(browser="/usr/bin/open")

Cheers,
Simon
