Fabulous forum i have stumbled across. I have a mac mini 10.4.11, im always waiting for it to do things. If i have firefox open (page fully loaded) and I change tabs to another page (page fully loaded) That spinning rainbow appears. If i go from firefox to emails, there is the spinning rainbow again to torment me! I basically use the mac for email/internet and storage of photos. No games on system. Bluetooth not on. Printer connected and dymo label maker It has been going on for around 3 weeks, it started as maybe once a day etc. Now it's 80% of the time! Any help would be great!
