// is created in main thread group. Thus, when certain
// AWT/Swing events are generated, the events will be
// dispatched through the wrong event dispatch thread.
//
// To fix this, we rearrange the AppContext with the frame,
// so the proper event queue will be looked up.
//
// Swing also maintains a Frame list for the AppContext,
// so we will have to rearrange it as well.
