I have a Sony Vaio laptop Win 7 top of the line* when I got it about a year ago.
Recently I have noticed that the scroll wheel doesn’t always scroll down a web page.
After much fiddling about (including trying a hard wired track ball) I realized that if the cursor is in the upper half of the screen near the center the scroll wheel works. If the cursor is elsewhere (bottom or sides of the screen) it might work once or twice or not at all.
Has anyone else seen this? Anyway you know of to get the scroll wheel to work regardless of cursor position?
Color me baffled.
