Well first let me state that I'm new to Mac and I just picked up my first Macbook and have a question about I-Photo. I have loaded pictures into I-Photo with no problems and gone into and out of it with no problems, however when I now click the icon to open I-Photo the window that would open is not there anymore. The bar across the top shows that I-Photo is open. Is there someting that I might have clicked by mistake?

Thanks in advance.
