Disable right click (turn off, or make it left click too) on OS X?

[ITASOR]

Is there a way to disable the right click on a 2 button mouse in OS X? Either turning it off completely or making it do the same as the left button will work.

Reason is that my grandma recently got a wireless Microsoft mouse which she likes, but keeps resting her hand on the right click button and pressing it. She has no real need for the right click function. Her iBook is running Tiger.

I know how to do it with the Mighty mouse, but not sure if it's possible on a different mouse. Does USB Overdrive enable something like this to be done?

Thanks

USB Overdrive has all you need. :)

under trackpad options in mice and keyboard, you can turn it off when another mouse is present

with usboverdrive or steermouse you can set the button clicks of any of the click functions, whether it be left, right, middle, double etc.
