On my Droid....before 2.2 update froze and ultimately killed my phone causing me to need to order a new one...I had the ATK icon on my main screen and all I had to do was tap the icon to kill the apps. On my wife's phone whenever you tap it, it brings up a whole the whole app and makes you select everything that way. I have tried setting hers to one-tap but it still takes me into the app to kill everything.
If anyone knows how to get it back to how I had, i would really appreciate it.
Also, if there's a better app managing app I would love to know about it.
