I recently uninstalled an app through the trash me app. The app had an icon that ran in the menu bar at the top of my screen all the time, but now the icon is gone. After I removed the app, there is now a sort of a ghost placeholder space where it was. I hold my mouse on it & the options get highlighted in blue to launch, or purchase online, but nothing happens when I click on them, because the app has been removed. anybody know what this is? is it anything serious?
