Java SE (Java Platform, Standard Edition)

Hi,

Recently, I've been working on a JavaFX 2.0. user interface with many
controls and menus.

Wherever there is a MenuBar (whit menus and menuItems) and a Textfield control in the same scene, when I click or call an event on the Textfield the menus and menuItems become unstable. I mean it starts to appear and dissapear with more frequency depending on how many times I clicked on the Textfield.

Also, I've got another problem but I read it was posted before(menuBar doesnt follow the location of the browser while moved or resized):

10120986 ]


I need to know if there is something wrong with my code..
Do I need to add some code, change it or this is a common problem?

I'm currently working on WinXP, netbeans 7.1, javaFX (FXML approach) and google chrome internet browser.

Here is an example:

I downloaded this code from this page and I just added the textField:
