When I activate Launch on both my Mavericks and Mountain Lion systems, a few of the application icons are (seemingly permanently) greyed out and marked "Paused" with an empty progress bar.
It isn't hurting anything, but it's weird.
Any idea why?
First, open App Store and try
Store > Check for Unfinished Downloads...
Mine said there wasn't any, but apps restarted downloading.
It seems as if the download was started from the App Store and it was paused for some reason. There are two ways that you can get it to not say that anymore.
Hope that helps!
