[R-SIG-Mac] Tcltk hangs when I invoke RCommander

[Simon Urbanek]

Andy,

please check that you have X11 installed. Also see whether clicking on the X11 icon in the GUI toolbar does start X11. Finally, try setting 
Sys.setenv(DISPLAY=":0.0")
before loading tcltk/Rcmdr.

If that doesn't help, please send me the crash log.

Thanks,
Simon
