What version of emphatic? Problems in car/DC mode were fixed in emphatic 2.03 (and are clearly documented earlier in this thread.) If you're not on 2.04 or higher please upgrade. If you are, then post your config.ini here so I can see what's happening.

As for the Hijack menu, I've asked mlord for a way to invoke the Hijack menu from within applications, and he says it's not doable.
