Every time I "manage applications" and select "running" on my Evo (2.2 OS) I find such apps as Stocks, Footprint, flickr running again, when just a few hours earlier I "forced close" them. I called Sprint and they told me to install Advanced Task Killer. Why do these keep running even after closing them? I know I can't uninstall them, but I how do I at least keep them closed?
