Mac OS X only
There is one more annoying bug was unveiled with Guild wars. Once I tried to enter mission I was dramatically surprised that it weren't available at all. Thus I asked for this flaw to 'normal' ms windows users they are reporting that suffered from the same but for sometimes. Therefore it seems we are still forced to be unable to play missions over a game. Hope to turn somebody's who may concern to clam it to the staff :)
Many thanks for support and understanding
