[DGD]Inherit_Program called twice?

Yes... it does help.  Thanks for saving my sanity.

Yes, it's the normal way of things to happen in DGD, nothing to do with
your OS or hardware. :-)

DGD only fully compiles one object at a time.

If you compile object A which inherits object B which has to be compiled
first, it'll finish compiling object B and then start the compilation of
object A from the start.

If you add debug statements in the path_include() driver-function you'll
find it calls those functions again as well.

Hope this helps,

Erwin.
