[R] 127.0.0.1:22381/doc/html/index.html won't start 2.

[Christian Hoffmann]

Dear All,

Sorry to bother you.

I am using Aquamacs 3.0a (GNU Emacs 24.3.50.2), newly installed, on Mac 
OSX 10.7.5 .

Somehow, on my mac even the newly installed R3.0.3 will mill endlessly 
after M-x R waiting for

127.0.0.1:22381/doc/html/index.html

to load. How can I find out, what is wrong with my configuration?

Thanks for considering.

Christian
