Hi all,

I'm testing Selenium for using into a project. I'm trying to create a very simple test
to be run as JUnit test case. The test loads google main page and try to write something
in the textbox. This is my code:

public class SeleniumTest
{
    private WebDriver driver;

    @Before
    public void SetUp()
    {
        //driver = new FirefoxDriver();
        driver = new InternetExplorerDriver();
        //driver = new HtmlUnitDriver();
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    }

    @Test
    public synchronized void Test()
    {
        driver.get("http://www.google.com");

        System.out.println("PageSource: " + driver.getPageSource());

        driver.findElement(By.xpath("//div/input")).clear();
        driver.findElement(By.xpath("//div/input")).sendKeys("test");
    }
}

When I run the test using FirefoxDriver or HtmlUnitDriver it runs ok, and driver.getPageSource()
returns the source of the page. But If I run the test using InternetExplorerDriver,
driver.getPageSource() returns an empty string and driver.findElement doesn't find
the textbox (I suppose it doesn't loads the page or the page is not loaded yet). Below
are the system details and the stack trace that I obtain when I use InternetExplorerDriver.
Is anyone else having the same problem? Is something wrong in my configuration? 

Selenium version: 2.17.0
