Really? I wonder what is wrong with my setup then. I am using

This is GNU Emacs (i386-mingw-nt5.1.2600)
  of 2007-07-07 on NEUTRINO

With R-2.6.0

And I have consistent problems with popups not popping. The following 
are consistent for me:

1.) ?something  where the function is in two different packages. 
?hyperGtest from GOstats is a perfect example.

2.) chooseCRANmirror(), which I have tracked down to select.list(). This 
won't work the first time I try. However if I kill it with a c-g c-c c-c 
then I can run it again without problems (e.g. select.list(letters) 
fails, but a c-g c-c c-c and an up arrow will then work).

If I load tcltk first, both will work without problems. But I am _not_ 
getting a tcltk listbox, just the usual Windows one.

Note that this isn't true for either RGui, nor running R directly from a 
DOS prompt. In both of those cases I get the popup without problems.
