As I wrote, my application runs at full screen  
(stage.setFullScreen(true)), while Ensemble8 doesn't. Anyway, if I run  
Ensemble8 and press the maximise button, the window doesn't grow to the  
whole screen, but leaves some room at the right and bottom border, just  
like I see my app.

Also - I changed Ensemble8 to run at fullscreen as follows:

% diff ./src/EnsembleFullScreen/src/ensemble/  
<         //stage.setTitle("Ensemble");
>         stage.setTitle("Ensemble");
<             //stage.initStyle(StageStyle.UNDECORATED);
<             stage.setFullScreen(true);
<             System.err.println("full screen");
>             stage.initStyle(StageStyle.UNDECORATED);

Same video problems: it doesn't cover all the screen. I can also see that  
the upper left corner of the application is off-screen (the whole window  
seems to be shifted upward and leftward). It's not a monitor overscan  
problem (at least, not only an overscan problem), since I can see the  
characters in the underlying console at their right place.

What I see is that keyboard navigation and mouse work with Ensemble2  
modified at full-screen, so I'll look again at my code about this issue.

If you want some more info, or screenshots, let me know. My app is also  
open source, so I can share the code, but I need to fix a couple of things  
so it doesn't depend on Maven snapshot artifacts (also, my Hudson is in  
maintenance and I can't confirm the app can be compiled from the outside  
world). I'll alter post to the binaries, so if someone  
wants to try it, just let me know.
