Unable to test the next web page by Html Unit Driver

Hi,

I am using selenium 2 in C# language. firstly i am using Firefox
Driver.

IWebDriver driver = new FirefoxDriver();
driver.Navigate().GoToUrl("http://www.google.com");
IWebElement element = driver.FindElement(By.Name("q"));
element.SendKeys("testing softwares");
element=driver.FindElement(By.Name("btnG"));
element.click();

With Firefox Driver, i can easily go to the second page after the
statement element.click(); and continue to test next webpage.

Now, i want to use HtmlUnit Driver(Remote) instead of Firefox driver because i
don't want to open the browser.

ICapabilities desiredCapabilities = DesiredCapabilities.HtmlUnit();
IWebDriver driver = new RemoteWebDriver(desiredCapabilities);
driver.Navigate().GoToUrl("http://www.google.com");
IWebElement element = driver.FindElement(By.Name("q"));
element.SendKeys("testing softwares");
element=driver.FindElement(By.Name("btnG"));
element.click();

but it does not go to the second page after this statement
element.click(); If i test the second page with some more commands then it shows error.
sometimes it gives error like "unable to locate
elements..............." or sometimes it shows error like "No response
from the server with url ............ "

so how can i go to second page with HTML UNIT driver?
i am using
OS-Windows XP professional SP 3
selenium--server-standalone-2.0b3.jar
browser-Firefox 3.6.17

please help me.

i am so sad for this problem.

thank you

problem might be in the version of selenium u are using try selenium standalone 2.2.0
