Rick, it looks like those prowebs order-totals are interfering with the OPC's "has the order changed" checking. I've requested a copy so that I can see what's going on.

I'm guessing that you set the OPC debug level to "full" to generate those PHP notify logs; it's normally sufficient to just use the "true" setting to get the OPC log generated. The "full" setting was added for additional debug and is not normally needed.
