Finally found a bug in eucontrol that provides sort of a workaround.

Add one application to the list in system preferences > Eucon, ports 1-4
Have that application open all the time while you work in mackie controlled apps.
Lock surface to that application in the Eucontrol Settings.
It will lock Eucon to ports 1-4.
Assign all your other Mackie enabled apps to ports 1-4.
(or the ones where Eucon won't work, §#3&##)
Application switching is a bit jumpy but seems to work here.

All these issues, as well as stability, should really be adressed!!!
Everywhere you go, you see trouble with Eucon.
Come on, Avid. You can do it.
