[R-SIG-Mac] rgl window problem

Wed Dec 6 19:07:19 CET 2006

Yes, I can confirm that this works now for me too.  Now if I can just  
figure
out how to get back to my 2.5.0 version for package development I'll be
happy.  I vaguely recall a tutorial by Simon about how to keep multiple
versions in play -- I'll try to track that down.  Thanks for the help.
