Z-order problem is specific to Windows (and I suspect to Vista/7 only). On this platform, a window can be shown above all other windows from the same process only if it is focusable, which is not true for JavaFX popups. Even if I call toFront() explicitly, the popup still stays below the main stage. I played with toFront() implementations in the native (call BringWindowToTop(), SetForegroundWindow(), apply various window styles), but the only workaround found is to temporary make the popup always-on-top with SetWindowPos(... HWND_TOPMOST) and then reset this flag back to HWND_TOP.

JFXPanel location is fixed as a part of the fix for RT-14135/RT-14292.

I will send this comment on to Paru who owns the context menu functionality in controls.

I have inspected the test code more carefully and found another problem: the popup is shown using mouse event's local x/y, but screen x/y should be used instead: contextMenu.show(vbox, e.getScreenX(), e.getScreenY()); The problem with JFXPanel's window location (0, 0) is still there and must be fixed.

Wrong popup position is caused by JFXPanel reporting it's location as (0, 0), not the actual on-screen coordinates. Z-order is a separate problem, it needs more investigation.
