Hello all,

I've set up my iMac to use a TV as an extended display.

I'm having problems keeping everything on the iMac as the main display. For example, I drag across a Movie to watch on the TV, but want to work on the iMac at the same time.

Every programme or file I open, opens on the TV instead of the iMac.
I've checked in the display preferences and the menu bar is allocated to the iMac, however anything I open seems to move the menu bar and dock to the extended display.

Why is this? How can I lock one display as the main screen? At the moment it seems to change between the two.
