I know i can close applications by pressing back button but when holding back button there are few applications.. i want to turn them off without touching it and going into application and press back button a few times.. Why is not there any X button to close applications? and that.. I want to close tabs on Internet Explorer.. but i am always using back button to quit. But when i look for Tabs on internet explorer.. there are alway the pages that i opened recently.. Can you tell me how i can fix those problems?
