Lately I've been noticing that some apps are running in the background when I've not opened them. Footprints, Voice dialer, Messages (I use handcent), Peep and Music are the ones I've noticed and (coincidentally) are all apps I don't use. I only notice them when using Advanced Task Killer and have to kill them. It's a new issue so is it possible another app I downloaded recently is to blame? Am i maybe just insane?
