Whenver I am typing in a window, say for example, writing an email in Yahoo! Mail, as I'm typing, the cursor jumps to wherever the touchpad or mouse is. In other words, if I have the little arrow pointing at a few lines before where I am typing, after a few seconds, and always in the middle of typing something, suddenly the little vertical line that follows where you are typing jumps to wherever the arrow from the mouse is.
I have no idea why it does this, and it doesn't do it on my desktop.
There is some "automatic" setting that needs to be changed, but I have no idea what it is, where it is or what to do about it.
I hope this explanation has been good enough for people to follow, but if not, please let me know, and I will try to explain better.
