MacBook Pro randomly creating blank emails
My MacBook Pro is randomly creating blank emails. I now have 14 blank emails off to the side. I can't close them. Clicking on the red dot does nothing. All I can do is click on the yellow dot and minimize them in my dock. My MacMail is open but I'm not using it when the emails are created. I've been searching around online for Christmas presents, scrolling through Amazon and several charities, etc. So I'll open a website up and be looking at something when boom, a blank email pops up. I'll minimize that and two more will be created. It's driving me nuts. I've tried closing MacMail and opening it back up, refreshing the computer, shutting down and restarting. The easy route isn't working. How do I get rid of these things? Included a screenshot of one.
Thanks for any help!!
