Gestures don't work in Safari

[Littleluk]

Hey there,
so I'm running Snow Leopard and the latest version of Safari 4. When I
enable gestures, they don't work in Safari when I right-click. I get
them to work, however, when I click both left and right buttons and
move the mouse. But then parts of my eMails are selected. I don't
think that this is right, since it works just fine in Firefox.

Thanks,
Luka
