Horizontal Scrolling in Leopard?

Ever since buying a new MBP in September, and using Leopard for the first time, I have been unhappy with the trackpad compared with my previous MBP running tiger 10.4.11.

But to keep it short and to the point, the main problem I have is the inability to scroll horizontally with two fingers. This worked in Tiger, but does not seem to work in any program under Leopard. Apparently there is supposed to be a "Check Box" under "Mouse and Keyboard" in system preferences to allow horizontal scrolling, however this is all I see -



Other than the many other things that bug me about Leopard, this one gets to me the most, as I notice it most often. So is my System Preferences strangely missing this check box? Or does anyone else have this problem, any help appreciated.

Well, it's not Leopard, because I have the following preferences with 10.5.5.

It'll have to do with the new trackpad features. You still should have horizontal scrolling though. Need input from others that have one of the new machines.

Hmmm, thanks for that, confused even more now, I am running 10.5.5, with a pre-firewireless Macbook Pro, so not sure why our "System Preferences" would be different? I will continue to search for info...
