I'm using an MVC Window on one of my pages. When I attempt to open the window in Chrome, I see a little gray rectangle where the "X" button should be. When I open it in Internet Explorer 11, I don't see any button at all. The button still works as intended when I hover over where the button should be. This only happens when I publish to IIS. Local runs on my PC work just fine -- I can see the "X".
Note that our remote web servers can't connect to the Internet at all. Could that be an issue? Is there a workaround?
Any thoughts? Thanks!
