[R-SIG-Mac] Totally frozen Gui and Forced Quit does not resolve.

Dear R-Sig-Mac,

I have not received any response to my request for help in unlocking my R-gui from its infinite loop.

To restate it simply.

1) I was running the newest version of R as of Dec 19th including the latest R-gui.
2) I needed to force-quit R with three R-scripts open.
3) On rebooting the R-gui the three scripts are reopened and the R-console is in its active mode without me being able to get its attention or close it without another force quit.
This is an infinite loop that I have not been able to break.

I can run R from a terminal window without the conveniences of the gui but as I have proceded from Dec 19 I have discovered that some of the conveniences of the R-gui are truly valuable and I would like to get back to a state where I can use the R-gui.

Is there anyone back from the Holidays yet who can tell me the minimum I need to do to break the infinite loop?

Re installing R from CRAN did not work.  There is some log that I need to erase to stop the system from recreating the problem each time I reboot R.
