For some reason i downloaded OSX Mavericks and installed it.
Now when I use MM it is Full-screening only to the laptop screen.
To make things worse (and most likely the cause of the problem ) the secondary monitor now has a status bar that stays visible when full screened (in Grand VJ) I found that when i used the Force resolution setting in GVJ that this made the status bar go away. but in MM its is still sending Fullscreen to laptop monitor.
And yes... i have checked the projector settings already,and set to the external monitor output.
Thanks in advance
