for some reason on my Dell 8600 labtop, when I type, the cursor will randomly go somewhere else on the page. I think it has to do with my cursor because when I click to type, I'll type for a second or a few and then it will randomly go back to the mouse cursor wherever it was, whether it was where I clicked to start the sentence or wherever it is on the page. This happens frequently and in all programs. Thanks in advance.
