When hovering over the damage rolled, the black pop up bubble has been randomly getting stuck on the screen. A similar black bubble in the top left corner of the page displaying the page name often also gets stuck, covering the default Select/Move button. In either case, forces the player to reload the page, as they can't see the text in the chat, or they can't use the selector. Has happened to numerous people in numerous games I've played, happens to me regularly while I edit my character sheets. Chrome, Early 2011 Macbook Pro, OSx High Sierra
