I am jailbroken on 4.2.1. Whenever I exit out an app that is ad supported the add bar stays at the top of my springboard. Sometimes it goes away after a few seconds and sometimes I have to respiring. What can I do to stop this?
I sometimes get the same problem. I respring and forget about it. It's no big deal. I don't know if you can fix the problem, other than buying the full version of the app, and sometimes trying to fix the problem causes an even bigger problem. Good Luck.
I also just say don't worry about it. It's probably there because the page hasn't refreshed yet. Try swiping to a different page or spotlight. See if it disappears once the page redraws everything.
