Dear Allan,

Yes!

> vp->setCamera(cam);

yes yes yes!

> IntersectAction *iAct = IntersectAction::create();
> iAct->setLine(mgr->calcViewRay( x, y ));
yes yes yes!

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa!

> pwin->getPort(0)->getCamera()->calcViewRay(l, x,y, *pwin->getPort(0));

> IntersectAction *act = IntersectAction::create();
> act->setLine(l);

Allan, thank you so much, that was exactly the problem, picking now works
like a charm! How comes that the SimpleSceneManager does not get informed
about the new camera?
Mange tak min ven!

P.S.: Dirk: The solution works with the 1.6 release...
