Does anyone have a fix for switching the mouse (even though Im not using a mouse, Im using the trackpad) selection switch from right back to left click.

This is for a new 2008 MBP that is having trackpad recognition issues, but first I have to resolve this right click issue.

I can open the SYSTEMS PREFERENCE then go to MOUSE (trackpad not recognized) but I cannot click on the LEFT CLICK option because I only have right click capabilities under that user.

I can log on using a different user, so if the fix is that route, any help would be appreciated.
