I thought of that after I submitted my post. But no, Talkback is not turned on. I turned it on, and then turned it off again, but it didn't make any difference.
And it's not reading me everything I touch. It just seems to be links and page titles, though I just tried it again in Pulse, and if I'm on a web page, and I click on a paragraph, that paragraph becomes outlined and it starts reading it to me. It's really irritating when I'm just trying to scroll the page.
The reading the page title thing happens in Chrome, Dolphin and the Pulse browser, so I know it's a system setting somewhere.
I was in a meeting this morning and made the mistake of clicking on
this link.
