I upgraded from 12.0 directly to 14.0 and then 14.1. The file was missing as of 14.0 -- and I had hoped that upgrading to 14.1 would fix it, but of course it did not.

Ah, good to know - thanks!

Nope, I'm all 64 here.

Nope, it's totally gone. And I don't seem to have it under the 12.0 backups, either. Could it be new since 12.0?

BTW, I appreciate the direct email on replies -- for some reason, I am not receiving mail directly from the list -- and I can't figure out how access my list settings on this list server to see if it's set to NOMAIL o something crazy like that...

Thanks!
