Cursing the cursor - help!

The past few days, my laptop cursor has been acting up. If the cursor hovers too long over a link or other window, it'll "click" on it by itself. Annoying as hell, and potentially dangerous.

I didn't find much help on google. I tried a couple things that I found: I changed the "sensitivity" of the touchpad settings. That didn't help. I uninstalled the touchpad device, and rebooted for it to reinstall. That didn't help.

Any ideas?
