Hello, I have G4 15" flatscreen Mac with a keyboard which seems to have a mind of it's own. Each time I try to type something the words come come out reversed when I try to delete (hit backspace) the cursor jumps to the http address field and when I press the space bar I loose the current page I was surfing on. I have to type backwards and is driving me mad. Has anyone come across a similar problem? Your help would be truley appreciated.
