Weird touchpad problem on Sony Vaio

[Ev0]

My wife's laptop is doing something slightly odd.

When putting the cursor over a vertical scroll bar on a webpage, she gives the touchpad a light touch for a single click, but instead of moving the touch bar one 'space' down it does it twice. Does it almost all the time but sometimes it does just one.

Here's the weird bit, when I have a go, it's fine, scrolls down on notch on the page. I can't get it to break for me.

Any ideas why the hell this would happen, can't see that she's touching it any differently to me!

very odd indeed, does the touch pad not have a scroll feature, should be able to just slide the right hand side of the pad with your finger like a scroll wheel, basically you press and hold then slide up and down.

it does, but she doesn't like that.
