[R-SIG-Mac] R Editor - syntax coloring

First, of all the new R-2.1.0 looks great on the Mac. It upgraded 
effortlessly and I am hoping to be able to try it out on Tiger later 
today, assuming the Police haven't cordoned off the Apple Store in 

However, I have come across a problem. The new syntax coloring option 
in the R Editor preferences looks great, but on large R script files 
(mine is 500 lines) slows the refresh down incredibly. Each key stroke 
take several 10's of seconds to action! It seems like the colorisation 
is redone for the whole file on each key stroke? I am running R on an 
iBook G4 800MHz with 640Mb and OS X 10.3.9 -- those of you lucky enough 
to have a G5 might not notice any problem!

As an aside, I note that R participates in Version Tracker but the 
version number comes out as 1.10 not 2.1.0. I understand the rationale 
for the Mac GUI having a version number of 1.10 but this is very 
confusing. Either way the current version should be at least consistent 
on Version Tracker.
