title: Error occur when clicking login button for IE only
body: <pre><code>  driver.FindElement(By.Id("inputUsername")).SendKeys("test");
          driver.FindElement(By.Id("inputPassword")).SendKeys("test2018");
          driver.FindElement(By.TagName("button")).Submit();
  </code></pre>

Upon clicking the login button error message "A exception with a null response was thrown sending an HTTP request to the remote WebDriver server" occured. But this only happen in IE. Other browser doing fine when executing the code above. Anyone know what is the problem with it? </p>
