There are cases when the various solutions you can find on the Web won't work. Despite what @Robert Aldwinckle thinks (I mean BS like "BTW note that regardless of what pointing device you use there will always be some "edge ****" because that is the way
that W8's UI works."), many people don't have the Mouse and Touchpad settings. We don't have Disable Edge Swipes either. Setting registry values like ActionType won't work either. And this doesn't happen only with a Sony vaio.
All it took in my case (Dell XPS L702X) is having one of the latest (and might I add "very buggy") Synaptics touchpad drivers, for which Dell didn't bother to provide Windows 8 drivers despite encouraging to upgrade to Windows 8.
As I've reported earlier today **here on this other forum**, you sometimes may have to resort to deleting, from the registry, some folders of the Synaptics driver. I'm guessing that most people, if not all, having trouble disabling the right edge swipe use the latest Synaptics drivers.
Suggestions such as "In any case another option would be to disable your Touchpad entirely (e.g. via Device Manager) and then attach and use a real mouse" leave me flabbergasted. Guess what, Mr Brilliant Mind, we though about it too. Actually, on Dell XPS
laptops, we used to use Fn+F3 to disable the touchpad. In my opinion, it is a very good touchpad. Thanks to Dell, Synaptics and/or Microsoft, Fn+F3 in Windows 8 turns on the light indicating that the touchpad is disabled, but that's all it does whereas with
Windows 7, it actually did disable the touchpad. It's a known problem. But I've bought a laptop to use a laptop; I use the desktop machine when I need to. So, if the screen of a laptop were to somehow fail, you'd say: just plug in an external monitor? Really
brilliant.
