Hi all, I've recently been having some weird performance issues on my 2 month old Macbook 1.83ghz 512mb and I'm hoping someone can help. I've done nothing different to the Macbook than I normally do (not that I'm aware of anyway) and today I've noticed some freezing and hanging when doing different things. At first I just thought it was under a heavy load after running Photoshop and other apps, but after a restart I noticed the freezing again, then I realised that it happens everytime I cmd+tab to switch between apps, the whole screen would freeze but I'm still able to move the cursor, it unfreezes after a minute or so. Another issue, probably related, is when I open FrontRow, it's severly laggy, taking up to a few minutes to respond and frequently freezing. The startup time has severly increased too, the login box normally appears straight away, but now it takes minutes to appear. I've noticed nothing wrong with CPU Usage and Memory etc. Hopefully someone can help, thanks.
