My mouse for my Imac got crushed. I bought a mighty mouse. it is suppose to automatically connect if you have snow leopard,as I do. but nothing. If not I'm supposed to click on the the drop-down....but wait I HAVE NO MOUSE!! how am I suppose to click on anything. I can get to the systems folder, but not inside. how do I get this stupid thing connected so I can use my 2,000 paper weight again. thanks. Oh, sorry for the rant.
