[R-SIG-Mac] R.app Help window problem with mouse click on PDF

[J ö rg Beyer]

Steven, 

I can confirm this problem for
  Mac OS X 10.4.6
  R 2.2.1 
  Adobe Reader 7.0.8

(I searched the help files and found some valid pdf-links to test -- the one
you mentioned is not part of R 2.2.1.)

It would be interesting to see if this behavior is related to a specific
Adobe Reader version. Anyone?

Cheers, 
Joerg
