Thanks; yes, I see that my 'mysql' host and other system tables are .ISM and .ISD files; I assume that means ISAM.
I was able to downgrade to 4.1, which I figured would be safe since the 5.0 server had never actually started; I'm going to stay there for now. If you'd like me to test a new upgrade path, I'll be happy to do that ; even if I were to lose all the mysql data, it would be no major loss. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
