I use two layer mode.
The apps that I use in the loader area doesn't matter.
I can pick any app for my loader shortcut, they all would disappear after a
reboot, or upon closing an existing app, ie: browser.
This bug didn't happen before update. I also notice a few users have the
same app disappearing problem as I do on the app store. Please fix. I don't
want to go back to default version and loose a the extra add-ons.
