Quote - ...erh..forgot to say that you must also lock them...!
I know this is not something one should have to do (Were lucky that DAZ stick to digital stuff
and don´t produce cars), but if it works, it works. I discovered this when using V3´s poses
on V4 and the same thing with the teeth( ???) happened. Otherwise it just worked fine!

hmmm...  I just tried locking the jaw and tongue parts as you suggested and ran the experiment I described above.  Locking the jaw actors did not eliminate the flying jaw problem, whether locking the jaw parts before or after applying PointAt for the eyes.  Did you really get it to work on V4 in an animation?
