Note: This is a problem I have never had before and I am not sure how to describe it in the title or here. Anyone may edit this to make it more clear.
I use Apple Mail on the latest OS X. This time, I sent a email to hundreds of people at once (these addresses are publicly known), just to have one of them fail and now I can't exit this menu, as seen here:
I force quit mail and opened it back up, just for it to happen again. I tried using tab to select "edit message," which would make this message disappear, but it didn't work. Do I have to factory reset Mail since I would need a ~4600p (34 megapixel) screen to select an option?][6
