thanks for your replies and sorry for getting back to you so late...
i turn the macbook on and off and it it still didnt clear.
i then thought it may because the battery was low, so i assumed it may have been a power saving type thing.
so i left it, and randomly clicked on it to find it working again!
i'm confused, but glad that it works again
thanks for your help.
(with regards to the green screen- i never had that, it was just the symbol you sort of get on the ichat icon, like a white video camera with a white cross through it and a black background)
