php is built again a 3.23 mysql client, not 4.1
This means you can't login in through phpadmin if you followed jfp's instructions to correctly configure mysql.
So: OLD_PASSWORD is the easy fix (instead of PASSWORD in the mysql setup).
There's a zip called something like php_mysql_mysql_41 - which is the up-to-date php_mysql.exe - but it doesn't work with openssl097e.
jfp says he'll do improved instructions and a new php_mysql.exe when he gets the chance.
