Thanks, Ronni!  That did the trick.  I had done a search for the  
plist when I was in Lion, but no entries were found. It didn't occur  
to me that it was in my home folder. Now that Finder is back, I tried  
the search again, and still no hits. It seems strange to me that  
search is not able to find it.

Whew, BIG sign of relief.
Thank you very much!
Pat
