Steve, don't worry about doing another version just yet -on my account anyway- it's just as easy to drop back to a 182 driver. I've tried various setting in FSX and nHancer to no avail. Maybe if new driver updates maintain this bug
it would be good to have different versions though.
Aerosoft release the PBY Catalina X
which looks stunning [in an odd/ugly sort of way]. May have to get this, despite the fact I'm not using FSX much, as its one of the planes that fascinated me as a kid.
Or through Flight Sim Store.
