I have a laptop with an odd problem. If I allow the cursor to hover over a link, it will sometimes follow the link as if I had clicked on it, but I didn't click.

This seems to happen at random times, not always. It can happen even if my hand isn't on the button.

It's not only in the browser. If I allow the cursor to hover over an icon on the desktop, it will sometimes select that icon, as if I had clicked on it. (It would take a double-click to open the item, and I haven't seen that happen.)

If this happened on my desktop, I would suspect I had a defective mouse, and I might try switching it with a different one, or I might try downloading a new mouse driver. But on my laptop, I don't have a mouse as such; I have a built-in pad and buttons, and I don't even know what that's called, or what the driver would be called, if there is one.

Any ideas?
