[R-SIG-Mac] Strange OS X editor window behavior

[Kyle G. Lundstedt]

Simon,
	Thanks for the quick response!  I'm a big fan of R on the Mac, and I  
really appreciate all your efforts on our behalf.  Regarding the  
syntax highlighting issue, I checked the R code with which I'm having  
a problem.  It's 841 lines and 4422 words.  Is that large enough to  
cause the problem?

Thanks,
Kyle
