This has been happening for a while now and appears to be getting worse. When opening just about any application, even logging in, I get the spinning wheel/pizza cursor. I ran the Fix Permissions and Repair Disc utilities from Disc 1 of the OS X install and they both did find some issues--I'd have to check the logs I suppose to see what was fixed. And I also have removed the spare HD which had almost nothing in it. I've also disconnected the Ethernet cable from the network and still the login screen took a while to come up (w/ the spinning cursor). This phenomenom occurs intermittantly, and can happen when opening any app: ITunes, IE, Safari, Mail, IChat, Thunderbird, Terminal window, et. al. This puppy has 1 GB of RAM (stock) and has a ton of disc space left (15 GB out of 60GB used). The spinning cursor eventually does stop but some times after 4-5 minutes! When this happens, even running "top" from a shell window takes a minute to kick in but nothing seems to indicate intense CPU usage. Nothing shows in Activity Monitor that would indicate a problem. Just ordered an upgrade to Tech Tools, hoping that will help. Any other suggestions?
