IE and native events

Right now I build a test with firefox driver and everything works fine. But I want to rework the test so I can also run it in IE.

Code:


public class SubmitIdea extends SeleneseTestBase {
   @Before
   public void setUp() throws Exception {
      WebDriver driver = new InternetExplorerDriver();
      String baseUrl = "https://website.com";
      selenium = new WebDriverBackedSelenium(driver, baseUrl);
   }

   @Test
   public void testSubmitIdea() throws Exception {
      selenium.open("/login.php");
      selenium.type("name=login_user", "admin");
      selenium.type("//*[@id='content-container']/div[1]/form/div[2]/div[2]/input", "password");
      selenium.click("css=div.center > input[name=\"submit\"]");


And it fails at the first selenium.type command. I think that the problem is that IE uses native events to perform mouse and keyboard operations in the browser. But I could not find any information about how to use those native events and actually how they look like ?

Native Events and Internet Explorer
As the InternetExplorerDriver is Windows-only, it attempts to use so-called "native", or OS-level events to perform mouse and keyboard operations in the browser. This is in contrast to using simulated JavaScript events for the same operations. The advantage of using native events is that it does not rely on the JavaScript sandbox, and it ensures proper JavaScript event propagation within the browser. However, there are currently some issues with mouse events when the IE browser window does not have focus, and when attempting to hover over elements.

Thats all the information I found about native events and IE. Anyone can tell me where I can find more information about this ? And maybe some examples ?
