I am creating a new ArcGIS Web AppBuilder (Developers). I have enabled the Splash Screen Widget. When I launch the WebApp, the whole screen becomes unresponsive and I am unable to click the OK button. When I move the mouse over the WebApp, the whole WebApp highlights, if I move the mouse up to the top of the Internet Browser header where the URL is, the highlight goes away. I am unable to click anywhere in the WebApp. I have tried and experienced this in Google Chrome and Microsoft Edge. Has anyone experienced this?
