How do I get rid of that annoying pop up when I'm writing an email?

Why can't Yahoo answer this, lots of people having this problem?

Sorry, this cannot be disabled. i did not see this pop up in Plain Text so maybe it is only available in Rich Text. Fortunately, Yahoo staff report that Yahoo is aware of this problem and their engineers are trying to fix it. Please see the page below for more information and updates. https://yahoo.uservoice.com/forums/210695-yahoo-mail/suggestions/5056928-constant-confirm-close-message-popping-up-while-ty

What the hell is Yahoo up to now? They've mucked about with Mail for months now! Don't they want us to use it any more! This 'Drafts' pop up is the most annoying thing EVER!!! How can we seriously compose a document with that keep popping up and distracting us from concentrating on the job in hand, Get a grip Yahoo and listen to your customers who have been complaining about you for months on end!

It's not the browser, it's the new improved yahoo that everyone got stuck with when they took away Yahoo classic and the other versions of Yahoo that always worked perfectly, or at least Yahoo Classic did anyway. The only way this and hundreds of other glitches can be fixed is for yahoo to scrap the new system and go back to the old one. It's similar to the situation with Obamacare.

Happening to me on both Safari and Chrome - any fixes for those browsers?

Yahoo mail has a pop-up that is causing a lot of rejection among its users. It is requesting every 30 seconds if you want to continue writing the email or if you want to save it as a draft. To avoid this pop-up you need to go to: Tools - Internet options - Security and check the box that says "Enable Protected Mode" then press Apply or OK and restart Internet Explorer.

Having the same problem and it started yesterday. I'm using Chrome and windows 7. Very annoying!!!

Same problem here on Firefox!
