Safari 6 Tab View Scrolling Seems Odd.

Hey Guys, I'm just posting because I'm wondering is this is normal behaviour, and if it is, wondering if I'm the only one that has a problem with it. The feature in question is scrolling in Safari 6 Tab View. In Launchpad, a short scrolling flick moves you to the next page, but in Safari 6, a short flick moves you (or me, at least) about 1cm, and it's totally jarring. However, using the arrow keys I can replicate the behaviour I'm looking for.

I know I can long-scroll through, but the inability to flick through them seems strange to me.

So, is this just happening to me, or an I using it wrong?
