Touchpad left button not working.

[Zazizizou]

Hi.
I have a Macbook Pro 13" the touchpad works well but its left button seems not to work properly:
I have no problem using "Tap to Clic" and "Secondary Tap" fonctions. However, when I CLIC on the left side (left corner) of the touchpad nothing happens though it works when I use the right side.
Is it a material problem or just configuration ?
Thank for you answers.

There is no "left" or "right" button, but you can look in the Trackpad pane of System Preferences to see how corners are set up. I don't think you can set up both corners at the same time.

That's what I'm saying, the left corner doesn't work in both cases, even when I set it as the left corner as the Right clic, it doesn't work !

Thanks for your time !

Is this the white/black polycarbonate MacBook, or the unibody MacBook?

Zazizizou reported it's a MacBook Pro 13", so it's a Unibody model.

Ooh, hey, who snuck that "Pro" in there when I wasn't looking?!

The reason I asked whether it was unibody or polycarbonate was because some people have reported trouble "clicking" on the trackpad in certain areas of the trackpad -- namely, the edges and toward the top of the trackpad button.

It seems a firm click in the center-bottom is a sure-fire way to always click, so it may be worth checking out your "clicking" habits to ensure that you're hitting the trackpad in a centered, balanced spot instead of off to one side.

This user is trying to use the lower left corner for secondary clicks. Primary clicks are not apparently a problem.

Well, I know where exactly I'm clicking. But the problem is that it used to work a few days ago. Now when I clic in the exact center of the trackpad, nothing happens ! And the primary click IS a problem as it doesn't work each time
Thank you so much for answers.
