Are you talking about the console or the editor?

This is a very strange error and it's just a soft exception so it  
should cause no crash - hitting <Esc> should get you back on track.  
But if it was a crash (with the famous "app unexpectedly quit"  
message), then there should be a  proper crash report - that would be  
more helpful in that case. Can you, please, run the debug version  
(from http://www.rosuda.org/R/nightly ) and send me the full report  
if this occurs again?

Not directly - it's hard to tell whether this is a bug if it's not  
reproducible ;). Did you run any computation in R while typing this?  
Was a Quartz window busy plotting something at that point?

Thanks,
Simon
