Mouse pointer keeps returning to the same spot

[Alex Angel]

So I have a monitor that I'v connected to my computer via HDMI. I close my laptop and begin watching youtube on my monitor but the mouse is all glitchy. It keeps returning to the same spot every 1 and a half seconds. At first I'm like "ok, maybe I'll go away". Nope, after 15 minutes it just gets really annoying because it's so hard to click on something that you might as well not be able to click at all.

Note: this problem only occurs when my laptop computer screen is closed
