iMac wired mouse not tracking up

Question

iMac wired mouse not tracking up

Hello everyone,

I have a two-year-old iMac with OS X 10.9.5. I have a wired mouse, not the bluetooth mouse. For some reason that I cannot discover, using the little grey ball allows me to scroll down pages but not up. So I have to go to the side of the window and move the grey sidebar up. It's a drag.
I may have changed the settings for my wired mouse, and that could be causing the trouble. After changing all the settings in different ways, I still can't fix it. I have cleaned the grey ball (upside down, rub around on clean paper), and cleaning the gunk off the track frame. Below are the current settings.

Can someone tell me what I should try next? I would really appreciate it. Thanks!

Try resetting the SMC, this may take 2-3 attempts. Please follow the directions in iMac SMC and PRAM reset

It worked! Thank you rkaufmann87! I had taken my mouse to the Apple Store, and they told me it was broken and had to be replaced. 50 euro for a new wired mouse; 89 euro for the new Magic Mouse. Harrumph. . . I really am very grateful. You are the best.

Your welcome. By the way, if you need to get a replacement mouse I have had excellent luck buying used ones (they appear new to me) from www.macsales.com.

Thanks for the tip. I will take a look. I don't live in the USA so would need a vendor who ships abroad.

Best, Carrie

Not a problem, OWC does ship internationally.

And off topic but related – we had a network expert come to our office to sort something out, and he told me by-the-by that I had my wired mouse set for left-handed people. The expert reset it. My husband was here, not me, and he did not make a note as to where that setting is. I have no way to know how it happened, but it is an oddity.

For the moment, I am scrolling like a boss thanks to you.
