Sorry about the enigmatic title but I couldn't think of a better way to describe it. My 14" iBook 1ghz has had a weird issue for about a week now. There is a certain spot on the screen in the lower right-hand corner where it just will not "click". It especially happens in safari, but I've noticed it in all browsers and apps. This happens in about a 2 inch square. For example, if I'm browsing the internet and there's a link I want that happens to be in that area of the screen, the cursor is a mouse pointer instead of a hand and will not click to activate that link. In order to get that link I have to move the whole safari window or scroll down until the link is in another part of the screen. I have restarted the whole computer and just started following the maintenence routine in this month's Macworld mag, (repair permissions, verify prefs, etc etc) and nothing has helped. Does anyone have any idea what's causing this? I have not installed any new software or updates that could be the culprit. Thanks.
