Q: Random page scrolling
In the middle of a session in Mail, my list of emails began scrolling up and down uncontrollably. If I moved my cursor out of that portion of the page, the scrolling stopped, but began to scroll as soon as I tried to highlight and choose a particular email message. I did a restart and now have the problem not only with Mail, but also with MS Word, Safari, and Finder pages. I have run disk verify (no problems), and repaired permissions. Since the problem began when I opened an email (from a trusted source), could it be a virus? If so, are there any Apple OS ways to check? Based upon earlier guidance from the Forum, I deleted my Norton Anti-Virus and now rely on the OS firewall.
Incidentally, this page is also trying to scroll/jump up and down so I hope I can get it to post.
Thanks in advance.

Thanks for the reply. I have been using a MS Intellipoint keyboard and mouse and as I started down the list above, I disconnected the Optical Mouse, using the trackpad on the MacBook. The problem went away. After removing the batteries (actually new) from the mouse and cleaning the air and blowing out the cavity, reinstalled the batteries and everything seems to be working fine, now. I'll print and keep your list on hand should the problem recur.
Appreciate your response.
