Get side scroll area back on laptop trackpad

A week ago I stupidly decided to download the Synaptics driver from their website and install it on my laptop, hoping it would give me more features. It didn't. Instead, it actually removed a lot of the 'features' and capabilities the trackpad had previously.

How can I revert to the older driver or add the side scroll area back to my trackpad? Is it possible to add a two-finger scroll?

I have a Toshiba Satellite laptop with Windows Vista.

Synaptics has this functionality as default, given that you have the correct drivers. See if you can find the following setting

Control Panel > Mouse > Device Settings > Synaptics TouchPad V... > Settings

Inside these settings, you can chose to enable the virtual scroll settings:

Virtual Scrolling > Enable vertical scrolling / Enable horizontal scrolling

To edit the are used for scrolling, edit this at:

Virtual Scrolling > Scrolling Region

If these options, aren't available, then try downloading the latest touchpad drivers (manufacturer specific) from the Toshiba website, otherwise try directly from the Synaptics site.

You could also explore the driver settings, to see if you can enable two-finger scrolling. I haven't seen this on my HP-based synaptics drivers though (seems I'm using driver version 6.xx, latest is 10.1.8).
