With Emacs 24.3.1 and ESS 13.05-1 this is the behavior I get

Execute
  library(Biobase)
in the iESS buffer (running R-3.0.1)

If I do
  ?Filter
inside the inferior R buffer, R hangs, no output.

If I do
  C-c C-v Filter
I get a buffer up saying

Help on topic 'Filter' was found in the following packages:

  Package               Library
  BiocGenerics          /usr/local/R/R-3.0.x/lib/R/site-library
  base                  /usr/local/R/R-3.0.x/lib/R/library

Choose one

1: Common higher-order functions in functional programming languages
{BiocGenerics}
2: Common Higher-Order Functions in Functional Programming Languages {base}

Selection:

This selection buffer is clearly new.  But I cannot seem to make the
selection inside this buffer.  Perhaps it needs some special key press?

So I don't seem to be able to actually choose which help page to look at,
no matter whether I use "?" or "C-c C-v".

Best,
Kasper
