http://androidforums.com – Hello all... Posting this in the rooted section for the EVO 4G because I'm rooted running MikG 3.11 on the phone and not sure if my issue is ROM related... Here is a screen shot of my pull-down notification menu: NO CLUE how this came about but I previously had NO recent applications listed in the pull-down notification bar. Now you can see Chomp, Camera, Phone, Jorte, etc at the top as recent apps. I've seen this option before...somewhere, somehow...lonnnnng time ago...but never wanted it. For some reason, it has recently appeared. I don't recall sloppily changing settings or anyth (General)
