Hi, not been on here in a while but anyway... My MacBook (2Ghz Core Duo, Mac OS 10.4.1) has decided to go funny recently - havent been doing anything different on it that I think could have caused the problems. iTunes and Safari seem to be causing most of the problems - iTunes freezes occasionally, usually if the computer has been left for a while then I try and select something quickly. Safari does the same. The spinning colour wheel thing just appears for ages. Usually a quick 'force quit' sorts this out however recently force quit doesnt seem to want to work. Then other stuff starts happening, such as the mouse not being able to select anything in finder, so I cant shut down the computer, or if I do shut it down it just sits on the blue screen for ages. Basically in the last couple of weeks ive had to force shut down the computer quite a few times due to this and it is annoying. Anyone know of any updates I might need or common causes of this problem? Thanks
