It is working again now, after I uninstalled, reboot, and re-isntalled.

So obviously I was wrong in my assumption of the updated dev-mode packages having an effect.

But thanks for the background info, I guess after PR1.3 I'll have a real reason to use Inception, I'd always said I would only go that route when I needed to, but I absolutely love ProfileMatic. Thanks for all your hard work.
