I diddled and diddled with the settings for the touchpad on my laptop but it was driving me crazy. I’d be typing along and look at the screen to find that the cursor had jumped to some other part of the document while I was typing. I’d have to stop and fix the document before continuing. Apparently, the heel of my left hand was brushing the touchpad while I typed and the computer was interpreting it as a tap, moving the cursor to wherever the pointer happened to be at that moment.
I think some computers come with a setting for disabling the touchpad while typing, but mine doesn’t. The solution, for me is a free utility from Paradisoft called “Touchpad Locker.” This little utility has a few settings, but I’ve been happy with it “out of the box.” When I’m typing it disables the touchpad for 750 milliseconds. That number can be adjusted, but it works fine for me right there.
UPDATE: I decided to up the lock out a bit, but when I did, it didn’t make any difference. I made it a ridiculously high number and still no change that I could tell. Then, when I rebooted, my ridiculously high number kicked in. Apparently, changes aren’t applied until a reboot.
