I recently tried to add two comments in rapid succession on SU and I got this error message pop-up window:

Screen snapshot showing error message pop-up window obscured by the “Chatting” screen element

As you can see, it’s unreadable, because the “Chatting” screen element is in front of it.

This seems to happen when IE8 is running in compatibility mode, at least that's how I managed to reproduce the issue.

Solution: check to see if compatibility mode is active, and if it is, disable it. There's two ways to do that:

  • if you see the compatibility mode icon next to the address bar, click on it:

  • alternatively, hit F12 to open Developer Tools, then select Browser Mode → Internet Explorer 8
