Logitech S10 - Mouse -> Changes Screen Brightness?

[blurb23]

I'm using a Logitech S10 Wireless Keyboard/Mouse combo.

The keyboard works fine (the media controls sync with iTunes beautifully). The mouse however, has some issues.

The clicking/scroll works fine. But whenever I use the scroll wheel and move it to the side (to scroll horizontally), the screen brightness starts to go down and doesn't stop. At what point is stops seems to be arbitrary; sometimes it'll go down only a few ticks, other times the whole way.

Anyone have any clue as to what's going on?

Try downloading the Logitech Control Center driver and see change the scroll wheel settings. See if that helps.

The control center is bugged in new versions of OSX, so I set about trying to find out what was causing the bug... successfully! First go to:

system preferences > keyboard + mouse > keyboard shortcuts

then scroll to the bottom of the window and locate the option that says 'display'. Completely disable this.

The problem is that macos thinks the left / right scroll options are f13 / f14 respectively, but they don't act in the correct way because they aren't actually buttons. Disabling this will probably disable the brightness buttons on your logitech keyboard BUT if you're using a macbook of some sort you can still use fn-F1 / fn-F2 to change the brightness as normal.

There you go, enjoy. Cheers.

EDIT: strangely enough, this also causes horizontal scroll to work correctly. Neat.
