If you right click once on the fullscreen panel and the context menu pop up then you right click again somewhere else on the panel *while the previous context menu is still visible* then it will cause a crash with : "Windows fatal exception: access violation" It seems to be caused by a crash in the QT event loop, trying to delete the existing QMenu within an event handler.
