Sorry, I confused manually and auto routed tracks (see the other post). So
it seems the autorouter acts according to the file format spec. Meanwhile
the manually routed tracks follow common sense ;-) Anyway, both should act
the same.

This is about manually routed tracks with vias inserted on the fly after a
change of layers. I tried the optimizer anyway, but to no avail. The mess
seems to occure only, if there are short tracks completely hidden under
the via.
