I have a problem: safari won't open. When I click on the icon on the screen it only bounces once and doesn't open up. The internet is working fine because the dashboard has the weather forecast on and I diagnosed connection and it says it is connected (it's wireless), If I try and open safari via the hardrive then it kind of flashes on the screen as if it is going to open but it doesn't. Does anyone know what the problem could be? (It's a macbook).
