[R-SIG-Mac] hangs on Open Dialog

Updated info:  I installed the latest patch version of R from 
research.att.com ,
and there are several things behaving differently.  Now I do not get any 
files opened when I open R, whereas previously all files open when I 
quit R re-opened (even if I'd used quit() and had a normal end of session).
In addition, the Window menu no longer displays windows (such as files 
being edited) which had been closed earlier in my R session.

BUT: I torture-tested by opening about 50 files inside R.  I then 
force-quit R, and then on restart,  R tries to re-open all the files 
again! I'm guessing this is desired behavior, to recover any lost work, 
but it's a bit unnerving.  At the very least, can you advise if there's 
a config file somewhere that I could delete to avoid this recovery mode?
