options(menu.graphics=FALSE)
looks like the right workaround.

>From ?par
 menu.graphics: Logical: should graphical menus be used if available?.
Defaults to TRUE. Currently applies to
select.list<http://127.0.0.1:25660/library/base/help/select.list>,
chooseCRANmirror <http://127.0.0.1:25660/library/base/help/chooseCRANmirror>,
setRepositories
<http://127.0.0.1:25660/library/base/help/setRepositories>and to
select from multiple (text) help files in
help <http://127.0.0.1:25660/library/base/help/help>.
>From the R ?menu and ?select.list, it is not immediately obvious why they
don't work from
inside the *R* buffer.  Please see if those commands will work correctly in
Windows 7
from Rterm outside of emacs.  If they work in the cmd window, then it is an
ESS problem.
If they don't work in the cmd window, then it is an R problem.
