I have a Macintosh [MacBook Pro] with multiple monitors. There's the built in laptop display and I additional have a Apple Thunderbolt Display and another third party monitor attached via Thunderbolt/DisplayPort adapter. This is a total of three displays.
When, in an application, I open a new window, the new window doesn't often open on the display I which currently had focus, but seems to open randomly across the three displays. That is I may have an open, active, foreground window on the Thunderbolt Display and when cmd-N'ing to open a new window it may open on the laptop screen or the third display.
How is Mac OS X deciding which display to open the new window on and can this be selectively changed to alway open on the currently active display?
