When I click to reply to an email I get a notice that reads Keep Writing?, I can't get rid of it.

A

AC Question

About 50% of the time I begin to reply to an email I get a notice that reads:
Keep Writing?
The choices I have to click on, Don't Save, Keep Writing or Save Draft. I emailed
Yahoo they couldn't fix it, I called Verizon tech they didn't know what to do either.

This notice is annoying and shouldn't be happening. How do I stop it. Is it a Verizon problem a Yahoo problem or a Motorola Droid Turbo problem
