I'm embarassed about the fact that this has been happening for so long and I haven't done anything about it but here it goes.
When I type, the computer stops my typing and puts the curser somewhere back into my already typed text. Why??????? I have to go back and erase the mistake and bring the curser back where it belongs. Yeah. It just did it again! How do I fix it?
oh you know what - i used to have the same problem
sometimes i still do depending on the computer
one way i made sure it didn't happen was by making sure the mouse cursor wasn't anywhere near what i was typing - b/c what was happening is the the blinking cursor (where you are physically typing) would move to where the mouse was. as long as the mouse was somewhere near the bottom of the page off to the side, this wouldn't happen.
other than that you should probably also maybe just call tech support if you still have it for free, b/c there must be some reason that is happening
