Can't delete empty folders in launchpad..
After upgraded to Yosemite, I rearranged my launchpad. Normally, when the last icon left the folder, the folder should disappear automatically. In fact, it did. But after I restart the computer, those empty folders appear again! I've try to restart it several times and those folders are still there...
Do you guys have this problem?
