Internet Explorer Wont Close Correctly

When i try to close the internet explorer window, or a tab within it, an error message like this is shown. It wasn’t doing this last night before i went to bed, and i have no clue what to do in a situation like this to remedy it… Does anyone know how i can disable the error message? (or fix the error itself)

Answer: Don’t use internet explorer. It’s the worst web browser there is. Just get Firefox and all your problems will drift away.

Exactly.Use anything that isn’t an IE
