Steps:
1. Go to an area where you can fly and start flying by keeping the triangle button on the controller pressed some time.
2. Open a window where the triangle button performs some action, like the party finder window
3. Press the triangle button and observe the window action taking place (i.e. refresh the list)
4. Also observer that the flying character also make an upward movement when the triangle button was pressed.
5. This also happens when the triangle button is used to close a window, like with the advanced search in the party finder.
6. Also note that similar behaviour for the circle button, which usually cancels a window doesn't have any affect on the flying character, while it has the fly-down effect when no window is open.
