Did you jump from 3.23 to 4.1? I thought MySQL likes us to go in steps -- 3.23 -> 4.0 -> 4.1 -> 5.0 with no skipping ahead. hmmm.

I do know that the SQL syntax changes from each version (no sub queries until 4.1 and logical ORs aren't really optimized until 5.0). but without the explain for these it's hard to tell what's going on. Maybe your indexes didn't get created?

If you're having problems with a query we need to see and explain plan for that query and a show create table(s)\G for the tables involved....
