Hi Everyone, I have a 2.0 GHz MacBook, running the most recent build of Leopard, that is just over a year old (and therefore unfortunately just out of warranty) which has begun to experience the following problem: Sometimes the computer runs fine, but very often the infamous "beachball" will appear and it will get hung up for up to two minutes, even when doing very undemanding tasks such as checking email. Force quitting usually doesn't work, as during this time the computer won't respond to the key combinations. The computer never completely freezes, i.e. if I can wait long enough it will eventually complete the task (only to hang up again a minute later). This seems to happen with all applications, so it is not app-specific. I have also made sure that no background apps are running and slowing it down. Any advice would be very greatly appreciated! Thanks in advance.
