I am not sure what they are called but often when you read articles there are links that when you hovers display a little box. It's not an actual popup, but a positioned element on the page.
I often move the cursor along as I am reading and I usually hit several in one paragraph each covering what I am trying to read. I am then distracted, taken out of what I am currently reading to click the close on the box, then I have to start at the beginning of the sentence often, triggering it again.
I guess I could learn to not follow along with the cursor, but it's a habit. Is there anyway to disable these?
