BUG ?? Eucon 3.1.3 still sees surfaces from disabled Network Interface

[bernhard]

In our Multi-Room Network we had to fight all the known problems of Eucon in a large network:

-Eucon automatically accessing wrong surfaces
-Lagging behavior if unassigned surfaces are available
-Loosing connection
-Surface not available

As a solution I installed a second NIC exclusively for Eucon and explicitly assigning it in Eucon Preferences (Win7 64)

BUT:
Eucon 3.1.3 still sees the surfaces from the disabled main Network interface
and is still able to connect and "steal" those surfaces.
