asked on

Scroll Wheel on Mac and Windows 7 scroll opposite directions

I have a Windows machine and a Mac. And have the same Logitech trackball on each.

They go the opposite direction and it's driving me crazy!

How can I change the direction on at least one machine to get them to be the same ??

Thanks!

Which version of Mac OS X? Lion? If so, Lion scrolls in something called "natural direction", aka "backwards". I'll bet Windows seems to scroll in the normal correction and Lion does not. Natural scrolling is why. Disable it from System Preferences...

System Preferences \ Mouse \ Uncheck; "Scroll Direction: natural"

Natural scrolling is an example of Apple thinking they know how people should want to use their products. In my experience it has been Lion's most disabled feature, with a 100% count among my clients.

I have Lion. But I can not find a checkbox containing "Direction" nor "natural".

Just "Zoom using scroll wheel while holding "...

How do I navigate to see this checkbox?
Are you using a trackpad, or a mouse. I have a trackpad on my system, so the prefs menu reflects current hardware setup.

I use a trackball with a scroll wheel in the middle.
