Можно выгнать ее за пределы экрана, вероятно меню не будет доступно. Я ее однажды загнал в левый верхний угол, нажимаю, а меню не видно. Нажимаю с клавиатуры, потом вверх, энтер, и ничего не происходит. А первый снизу пункт - выключение компьютера.iGrok писал(а):Antoniary.. Но она все раво будет работать при вызове с клавиатуры.
