I'm sure I'm not the only one who has seen this. I often run with my iPhone with Runkeeper Pro and Couch to 5k running backgrounded, as well as the iPod playing and sometimes I check my email or fire up Tweetie. I often notice though that I can't get back to the home screen because one of my apps (Couch to 5k usually) won't go away. Once I finish my run, I can kill it off with Kirikae and reveal my home screen again, but it's annoying. Is there a solution to this, or do i have to just live with it?
