Now that I have your reminder, I can see that I've got
the fix in my notes dated 27Jun2003. Too bad I wasn't
looking back that far before I sent my note to the
list. I'm glad your memory is better than mine.
Sorry to bother you again, Yoav. I hope your holidays
were good, and my best to you for the new year.
Thanks again for watching this list. Sincerely, MOD
