Thank you for your help. I got the thing to work prior to receiving your input by doing the often used PC fix …. I shut the Mac down and re-started it, and bingo, problem solved.
First step, turn mouse off and turn it on again. That may fix it before attempting the more drastic steps.
Yes, turning the mouse off and on again worked – thank you!
I first noticed this problem in mail, and closed the application and voila! Then the same problem occurred later in Safari. Closed that and reopened and scrolling started again!
I also noticed the no-scroll in mail. Did what Bill above said — turn the mouse off. Wait 10 seconds, turn back on and it worked. Thanks Bill.
Restarting fixed the problem for me. Thanks!
