Popup shows on Display #1 always

[rob-watts]

In multiple display situations, the popup always shows on the display windows considers the main display from Display Properties, Identify Displays.

If the app is running on another monitor, the popup may not seen (or is likely to be missed).

Any chance you could modify the popup method to detect which display the app is running on to ensure its shown on the same monitor as the app?
