I was surfing on e-Bay with no problems when the mouse pointer turned into a colour spinning disc and I couldn't do anything! In the end (after about 5 minutes) I resorted to switching machine off by holding power button down. Anyone able to shed some light on this for me? I have a 20" imac with c2d and 2 GB RAM machine is only weeks old and I am a recent convert! Many thanks... Wattso
