I have read article "Application VS Stage VS Scene VS JFrame ", and I got the same problem,
in my application, I need tow windows work concerently. I use one Application, and create tow Stage
It works will so far, BUT ONLY ONE STAGE CAN REPAINT(refresh), the other one just frozen, why?
how to make two windows work concerently?
There is also an example with source code in the ensemble sample app: http://download.oracle.com/otndocs/products/javafx/2.1/samples/Ensemble/index.html#SAMPLES/Scenegraph/Stage/Stage
Here is another example: https://gist.github.com/1926196 PopupExample
