Apps in dock bouncing but not launching.
It was working five until few weeks ago. The problem is "Apps in dock are bouncing but not launching".
Apps like Mail, Safari, Firefox, iPhoto, iTunes, Skype, QuickTime, Vlc, Address Book, iCall and even Google Notifier on the top Bar. I can click on them again again but nothing. Only way to open them is to Log Out and Log in again. But in this case not all of them are working yet. I have tried with Apple Apps to delete in Library/Preferences - com.apple. .... but it doesn't work.
I know the easiest way to solve it would be just create this second account again but I wanna find out what's going on here.
