Launchpad icons stuck on desktop
Running Yosemite (10.10.2) on a MBP Retina 15" 2013 with 16gb Ram.
Its been happening consistently now where I would go to Launchpad, search for an app and click on the app. The clicked app would then stay on screen. So now I have a floating, non-interactive icon of the app superimposed over all my windows and apps. Restarting OS X will get rid of it but that's a pain every time it happens.
