Two Monitors and Workspace problem

I imagine that I’m not the only one with 2 monitors on my Mac Pro.
I want the mixer to be on the left monitor and the project on the right monitor (my main monitor a Apple Cinema Display).
So I create a workspace just that way and save it as a global workspace.
Next time I open Cubase 8 I find the project on my main monitor AND the mixer BEHIND the project, and nothing on the left monitor.
This is NOT the way the workspace was saved!!
I think it’s a bug.
