After updating to iOS 4, I realized that everytime I try to exit an application the app just goes into multitask background. i don't want it to be in multitasked but to exit it. For example I'm using Safari and I want to exit it (not minimize it) so i click the homebutton but Safari is still running in the background. So then i would have to manually close it but clicking the homebutton again to close it. is there anyway to choose when to close apps and when to put them in multi tasking mode?
