Sorry - forgot to mention the following. Consider upgrading to 4.6.2 on PG 7.2.4 which is the current best stable oacs version. If you are running 4.5, you are missing out on some excellent performance enhancements made by Don and other members of the core development team. I just completed a full test of 4.6.2/7.2.4 and it really works beautifully. The next step is to bring the platform to compatibility with PG 7.3.2.
