Hi, I don't know what happened to cause the problem (might have been the clearing of User Cache) but for some reason my mac is acting weird. For example, when I have an application open and I click the red button, it used to just hide the application, now it just quits it completely. Also, Microsoft Office 2004 opens fine and lets me view my documents but whenever I try to print or save as PDF, it just quits without any error messages. Why might this be happening? Thanks!
