You may want to use the “effective topLeft” though. Otherwise the title bar of the window could be off screen.

Thanks,

But I've just discovered that on a multi-monitor setup as I've described, the toolbar isn’t even visible it’s so far off. So in this case 0,0 is not the top left corner of the main monitor. How so I arrive at that point? How do I determine the actual middle of the screen? Since I don’t understand all the dynamics of how these things are being determined I have not been able to arrive at a work-around to place things where I’d like them on the screen.
