A DESCRIPTION OF THE PROBLEM :
I'm testing JavaFx and I tried a simple HtmlEditor demo. Everything seems ok, the editors appears, I can type text, but if I click on a pull down menu (ex. to change the font size) the application freeze, I get a black rectangle where the menu is suppose to appear.

I'm on Windows 10 64Bits, JDK 8u65, with IntelliJ

I Tested on another windows computer, with a fresh Java install same problem
I tested creating a Java application, and a JavaFx application same problem

I Tested on a mac (recent, bought 2 months ago), the demo works
perfectly
