As the posting guide says, there is no such version, and this list is 
only for current versions of R: you were asked to upgrade *before* 
posting.

But it does work correctly in R 2.11.0 on my Linux box.

This is all about the version of Tcl/Tk, as someone told you 
yesterday.  Tcl/Tk is not part of R, even if on the binary platforms 
we provide a build (which on Windows has not changed since R 2.7.0). 
But we don't know what your platform is, as you ignored the posting 
guide.
