I am (still) creating a website to create websites. In there, I have a couple of comboboxes. Sometimes the ComboBoxes appear to loop, or something.. Visually what happens is that, two of, the boxes loop, both flicker rapidly. The application does not crash, that is it does not shut down, nor is it responsive. In my IDE (eclipse) I looked at the thread running, and it appears to be the fault of "Thread [JavaFX Application Thread]". When I suspend that thread, I first see
Thread [JavaFX Application Thread] (Suspended)
WinApplication._runLoop(String[], Launchable) line: not available [native method] [local variables unavailable]
WinApplication.access$100(WinApplication, String[], Launchable) line: 29
WinApplication$2$1.run() line: 67
Thread.run() line: 722

While going through (using eclipses F5) I get

Scene$14(ObjectPropertyBase<T>).set(T) line: 161
Scene$KeyHandler.setFocusOwner(Node) line: 3470
Scene$KeyHandler.requestFocus(Node) line: 3516
Scene$KeyHandler.access$2400(Scene$KeyHandler, Node) line: 3468

Often I see the equals class, otherwise I see nothing...
The JavaFX version in Eclipse is 2.1, recompiling (and deploying) via NetBeans I use 2.2. Both have the same problem.
