Have you ever had the misfortune to have been to fix runtime error? This happened to me recently and it was not an easy thing to fix. A runtime error is a hardware or software problem that will prevent your Internet explorer from working properly. A runtime error is normally caused when a website chooses to use html code that is not agreeable with your web browser. There are many different ways to fix this type of an error and you need to make sure that you choose the right way before you choose any.
