Green dot on screen
I have a 900mhz ibook purchased in August that has gone through normal usage, nothing extreme, and has been given the best of treatment, hasnt been tossed around or anything of the sort. But today after watching the last half of a dvd and a little net surfing i noticed a green dot on the mid right side of my screen. What is the correct term for this problem and what can i do to fix it? Is there any utilities? Thanks in advance.
