Hi, Ronni,

Thanks very much for your reply. I just did as you said, deleted the 
com.apple.LaunchServices.plist, rebooted, but it did not solve the problem, and 
the plist has not been recreated.

I see that there is also a directory called com.apple.LaunchServices and in it 
is com.apple.launchservices.secure.plist.  I did not do anything to this.

Do I need to do anything to recreate the plist?

I have used Terminal successfully for a few things in the past. I believe I can 
follow instructions to fix things.

Pat
