No right-click with USB mouse

I have a 6-month old MBPro with up-to-date Leopard. I have a new USB keyboard with USB mouse plugged into the keyboard.

The keyboard and mouse work perfectly when plugged into my iMac (also up-to-date Leopard).

When I plug the keyboard with mouse into the MBPro, everything works except right-click. It does absolutely nothing.

Any ideas as to how I can fix the problem?

You will have to set your mouse button preferences in your System Preferences under Keyboard/Mouse.

That's strange. I've never had to do that. Is that a new thing with the MacBook Pro's?

Click to expand...

This is my first MBP so I'm not sure. But that was the right answer... the installed default was no right-click.
