Thanks Lee - will have a look. I Got it working in CS6 in the meantime.
I've been so used to using DataAssist, that I see a glitch across all my versions of DW - when I drag a field from the Bindings panel into a page, it doesn't do anything.
The mySQLi extension looks pretty good, not least for future proofing against PHP6 when it happens, but I still feel a bit in limbo until DataBridge is updated.
Have you found a good workflow for creating all your pages with mySQLi with all the insert, update, search and results pages?
