Mouse shortcuts?

Is there a way to modify the mouse shortcuts on Tiger? The reason I ask is because I'm using a 3 button mouse and whenever I move my scroll wheel to the left or right (normally used to scroll left/right) it changes the brightness. This wouldn't be so bad but it only move the brightness down, both left and right. I know I found a way to disable it before but since I did a firmware upgrade I can't seem to find where to disable it anymore

any help is appreciated

Where is the mouse from and did you install the drivers?

it's a Logitech wireless mouse (and keyboard combo) and no I did not install the drivers. I'm new to Mac and I believed the propaganda that Macs have all the drivers you will ever need preinstalled

Well it generally works doesn't it?

If you want to use special features of a non-standard peripheral, you will need to install the drivers.

well, I just searched for my drivers at the Logitech website. I found my mouse but they don't have Mac drivers listed

And I don't think it's a drivers issue, becasue like I said I know I disabled the brightness adjustment before, just a few days ago actually, but then I did a firmware upgrade and also the 10.4.7 update and now it seems like the option just vanished :/

You can use a 3rd party driver such as USBoverdriveX to add mouse button shortcuts...
