Trackpad functionality not working in Iphoto

Hi All,
Has there been a change to trackpad functions in Iphoto. I see there are now back/forward buttons, but I am no longer able to two-finger swipe between photos or zoom in/out with the pinch. Can anyone help.
Cheers

Latest iPhoto here with a multitouch trackpad:

- 3-finger swipe left/right switches through pictures
- pinch zooms in/out, but only if you're in edit mode
- rotate works as well

Have you checked your System Preference settings for the trackpad?

System settings

Hi,
Yes, sorry I should have listed what I have tried. Nothing in system settings in this OS (10.6.5) offers options for 3 finger (Only 2 finger h and V). No options in Iphoto 11 to change trackpad. Can I uninstall Ilife 11 easily.

Do you have the old trackpad with a button, or a new buttonless trackpad?

Old trackpad

Ive got the old track pad with a button......
