I love using a laptop, on my lap. I prefer small notebooks as they are easier to carry and the screen is big enough when it is so close to me. BUT I hate the way in which at random my wrist or a trailing thumb will activate the touchpad while I am typing, and boing, I am now entering text in the wrong place. The cursor jumped :(
[Now I get annoyed with users who claim: “the machine/software just did” this thing I did not want done. I keep telling them that the error is theirs. So, I fully accept the cursor does not in fact jump around at random, it just seems that way. The effect is indeed caused by inadvertent brushes of my wrists or thumbs – but it is nevertheless annoying as all get out!]
There is a cure, a small utility from Google called Touchfreeze. It seems to work well, it turns off the touchpad while you are typing, but turns it on once you stop. I’ve been using it for a couple of days on both my netbook and my ultrabook and it just works. So far no worries where the trackpad is “off” when I want to move the cursor, and no more “jumping cursor” :)
It is just brilliant!
Google describe it like this:
