Mix Console on secondary monitor

i would like to post a bug, regarding using Mix console - shortcut F3, when i move the console to secondary monitor, set up the console, close mix console window and press F3 again it will open the mix console back on my primary first monitor.
It happens on all cubase 8 version updates, 8.0.30 and 8.0.35

in version 7 there was something like “stay on top” and everytime it opened on the same place.

i am on iMac 27" late 2010, OSX 10.10.5, 16gb ram.

Thanks for solving this issue.
