Synaptics touchpad lost scroll function  

Hi there,

I have a Toshiba Satellite A300D that came with Vista, but recently my hard drive died and I installed Windows 7 64bit with the new one. My problem is that the Synaptics touchpad lost its scroll function, and Toshiba doesn't provide the drivers for Win7, only for XP and Vista (and those don't work, I've tried it).

What can I do to make it work again? Thanks!
