[R-SIG-Mac] Can't open files in 4.0 or 4.01

Well, dang me if today I wasn't able to open a file in R. -- but only 
once or twice, and then I get the 100% CPU hang.  Same result if I 
double-clike the file in Finder or use the R-menu "Open" dialog.

R- version 4.01, and to my knowledge I didn't change anything of import 
in my Mac's system or set of applications.

If you can suggest a logfile or other tool I can pull info from to show 
what happened, please do so.

thanks
Carl
