I just installed Lion over Snow Leopard. I was trying to rearrange the icons in Launchpad into folders/groups. It worked for a while, but sometime in the middle of rearranging I could no longer take previously foldered/grouped icons out of the group I had previously put them.
I performed the killall tutorial to reset Launchpad, only to have to start over again. I tried restarting, etc., but I ran into the same problem again after a while of rearranging.
I cannot find anything online regarding being locked out of rearranging in Launchpad. Has anyone else had this problem? How can I fix it?
