The first batch of MSI Wind handhelds shipped with Synaptics touchpads offering a “touch scroll” feature which allowed you to scroll across pages by dragging your finger across the sides of the pad. Unfortunately, many people (including a few friends of mine) had huge problems with this feature – which is why MSI switched to cheaper Scentelic touchpads lacking the touch-scroll capability.
MsiWind.net users unhappy with the lack of this feature decided to take matters into their own hands: they purchased a similar touchpad and managed to get it working on their MSI Wind. While the upgrade will likely void your warranty and requires a complete disassembly of the unit, I can fully understand them as the touch scroll feature really is insanely useful.

I would be happy if I could just get the darn touchpad NOT to act like I’ve clicked the left button with the slightest of touches. There’s no way to turn that off without switching drivers, and my first try resulted in my touchpad becoming completely unresponsive.

Does the wind run linux? If it does install syndaemon! It allows the user to disable the touchpad when a user is typing, etc, to disallow the touchpad from clicking.

Hi,
one can IMHO turn this off somewhere in the Synaptics panel on Windows!
If you need help, just let me know!
All the best
