Thanks for fast reply, looks like I did misunderstood the DataBridge 1.2.0 - , eCart 6.0.7 -, Design Extender 1.1.9 - and Free Tools 1.1.1 Release Notes which mention: Updated for compatibility with MySQLi Server Behaviors.
Anyhow the MySQLi Extension is great, so I look forward to the upgrade of DataBridge and eCart to MySQLi :-)
