launch pad just stopped working
So Launch Pad just stopped working. When I use my track pad gesture or when I go to Applications and try to launch it the only thing that happens is the desktop picture goes out of focus--but no Launch Pad. I use this application ALL the time. Any ideas what's going on or how to get it back? I've verified my disk and repaired permissions but to no avail.
Thoughts and help anyone? Thanks!
