This would be interesting to know, doubtless, but please note that MySQL 4.0 is either no longer supported or will reach that status in the immediate future.

If you find reasons to believe that any problems you're seeing are a MySQL problem, please let me know. Greg -- See complete headers for address and phone numbers
