OK, i've got a workaround for that: this is part of an email sent by agnitum support center to an user who was experiensing the same bug. It's work for a couple of users and me too. Waiting for a new outpost's release fully working on 7. :D
thanks for posting your solution! It's very usefull for me! I spent all night looking for solution! by the way have you got any way to keep outpost working during videogames session?
