apps and ATK....

[2kidz]

just wondering, why is it that when i do simple tasks, such as open my texts (which involves NO apps) and then i go to ATK, there are apps that are killed??? how is this possible? i can see if i was in an app and then tried to use ATK but the apps that are being closed werent even being used??? can anybody explain this?

also, why is it that when i receive a text, i will open via either handsent or messaging, my light will blink red? why does this occur and how can i stop it from happening, i mean, i have READ the flippn' text!!!!
