Multi display change

Long time I always have been able to play GW2 in my multimonitor setup as I play other games. Since 3 updates, it never opens in the display I use to play the game. It always force relocate to the main display. I understand people might not like multiboxers and what not, but if the game will do these things to avoid a problem and bother other people in the process. As there is no answer from the support, I am just leaving it.
