Changing Scrollwheel Click Functionality

Fongpi,

I hope that coming to Mac has been as good for you as it has for me. Anyways I don't know of away to assigning "open in new tab to the third mouse button" (aka the button under the scroll wheel). However I may be able to help you with this issue. First I don't use Firefox but in Safari the default for opening a link in a new tab is hold  (Command) and left click on the link. I'm assuming that it would be the same in Firefox.

As for turning off the Expose loading when you push that button. Goto while the mouse is hooked to your Mac (System Preferences)/(Expose & Spaces) in the (Expose) tab, change the (Middle Mouse Button) to "( - )" it should be located near the bottom right of the open Preferences window. *The reason that the mouse has to be attached to your Mac before you open System Preferences is because Mac OS X automatically hides the unusable fields.

Hope this helps with your issue.

Strangely, what you are looking for is in Exposé's preference panel. Honestly, I would not know why Apple put that there but it is.. You can assign/de-assign some functions to mouse buttons from there but Im afraid this will not change Firefox's behavior. At least you will be able to disable the DashBoard spawn.

Good luck

Hello,

System Preferences/Keyboard&Mouse. Click the Mouse tab. Click the Scroll wheel pop up menu. Either turn it off or reset for another function???? That doesn't work?

Oooops, my bad. I assumed this was a Mighty Mouse which I shouldn't have... sorry. Not sure how to configure the Dell. Perhaps someone else can help you.

You're going to have to get Dell to write drivers for your mouse or use a third-party driver like USB Overdrive.
