[R-SIG-Mac] Using a second monitor, running R under Unix

[Simon Urbanek]

Thanks, John.
This this should be now fixed in the R24-branch (e.g. fetch the  
installer from http://r.research.att.com tomorrow). It is a quick  
hack, legacy Quartz windows will now appear in the center of the main  
screen.

In general that device (Quartz in console R) is unsupported and will  
go away very soon, because it is a legacy from very old times and the  
API it uses is now deprecated and Apple will remove it from future OS  
X versions. We are working on a replacement device for R-devel, but  
it won't work in R 2.4.1, so stay tuned and I'll let you know when  
it's time to test the new beast ;).

Cheers,
Simon
