how to remove sticky (permanent) notifications from notification bar? I have a buggy app installed in my phone, which sometimes creates permanent download progress notification with animated icon but fails to remove it from notification bar by its own.

I tried to remove the notification manually (swipe it off) but it is sticky and can't be removed. I tried "clear" option in notification bar, but again no success and it is still there! I even stopped that app which created the notification, but no change.

The only option that I have to remove such sticky and buggy notifications is to restart the device, which is very unpleasant.

Which app, hack, command, gesture, etc... I can use to remove that sticky notification?

*My device is Sony Xperia S running ICS 4.0.4 stock ROM (rooted)
If you're using Jelly Bean, then in manage apps, you can turn off notifications for the specific app. Keep in mind, this will turn off all notifications for the app.
