I have a laptop (a Samsung Series 9) with a Synaptics trackpad, and I have Windows XP on it.
One of the nice features of this trackpad is that it allows you to scroll by placing two fingers on the trackpad and then dragging them up or down.
But the really annoying thing is this: Instead of acting like any other scroll wheel in existence and sending scroll wheel events to Windows, for some reason the Synaptics trackpad has special logic for scrolling. It changes the mouse cursor to a drawing of a scrollbar, and then scrolls the window itself using a seemingly proprietary mechanism.
The problem with that is that this scrolling doesn't work on all apps. For example, it doesn't work on GTK-based apps, which I use a lot.
I really have no idea why the Synaptics developers chose to reinvent wheel-scrolling, at the expense of their users…
Anyway, is there a way to make my trackpad send standard scrollwheel events, so it'll work in all apps?
