I recently updated my operating system using Leopard. It installed fine, no blue window of death. I enter password and it goes to the desktop. Now i get the icons along the dock but nothing shows up on the desktop. the spotlight bar doesnt appear. after about 20 mins the time, battery life etc show up on the top right corner but with no bar behind it. no icon appears for spotlight either. after about another 20 mins a message comes up saying spotlight quit unexpectedly. its a continuous cycle. is there anything i can do to fix this? i cant open any applications at all.
