How to remove an empty group in Launchpad I installed Google IME and uninstalled it. Then, as shown in the image below, an empty group is left in Launchpad. (I think it should have been removed automatically when the group became empty.) How can I remove the empty group manually?

OSX 10.10.2
Previous answer didn't help me on Yosemite - when I dragged app into the empty folder the app just disappeared for a while and the folder was still there, empty and disturbing. But then I've found a way to fix it without resetting Launchpad:

Click and hold any random app until all icons start shaking, then drag the app on the folder, DON'T RELEASE, and drag back into its place. Right after dragging back the empty folder has disappeared.
