Ok im using a new Imac 20" 2.4ghz. its running on lepoard. this is my first Mac and so far im not that impressed. It was starting up fine for about 5 days, but now im getting a flashing world in the midle of the screen for about 5 munutes then it starts up. I have read about a flashing question mark but cannot find any reference to what I have. They Probably just changed the icon, but I want to make sure. Any ideas much appreciated. Cheers people.
