Initial positioning of Dialog

[ngalarneau at ABINITIO.COM]

Scott,

When you say it works for you, which java are you running?
 - Java 8 (1.8u25) with openjfx-dialogs-1.0.2 like Pete
 - Java 8 update 40 pre-release
 - something else?

Using the released 8u25 with openjfx-dialogs-1.0.2  I, too, have seen the 
dialog pop on the wrong display.

Ah, I the controlsFX code must be doing something to position the dialog. 
Perhaps you can step into the code and see what it is doing.
The behaviour without a owner appears to be the standard behaviour - 
centre on the screen.

 However, if I move my main app into my secondary display, the dlg pops up 
in the center of the main display. This seems like a bug.

correct display based on where the parent window is.

wait a bit before setting the opacity to 1. Even that was done in a couple 
stages with runLater.
