What steps will reproduce the problem?
1.Have nuget reference to WebDriver 2.35 and WebDriver.Support 2.35
2.Simple test that hits http://www.google.ca/
3.Try to click on the Signin button on the Google home page

What is the expected output? What do you see instead?
Expected to see the "sign in" button clicked and the Google login screen show up

Actual:
Button not clicked. 

Selenium version:2.35
OS:Windows 7
Browser:Firefox

There is the sample I made,

        [Test]
        public void Selenium235Test()
        {
            IWebDriver driver = new FirefoxDriver();
            driver.Navigate().GoToUrl("http://www.google.ca/");
            var signin = driver.FindElement(By.ClassName("gbit"));
            signin.Click();
        }

Definitely happens with the .Net driver. WITH 2.35 but not with 2.33 

Simple repro on windows 7. Start Powershell and type the following

Add-Type -path  [YOUR PATH TO selenium-dotnet-2.35.0]\net40\WebDriver.dll

Then paste this: 

$driver = New-Object -TypeName OpenQA.Selenium.firefox.firefoxdriver              

$driver.Navigate().GoToUrl("http://www.google.ca/")
$signin = $driver.FindElement([OpenQA.Selenium.By]::ClassName("gbit"))
$signin.Click()

But if have 2.33 type 
Add-Type -path  [YOUR PATH TO selenium-dotnet-2.33.0]\net40\WebDriver.dll

and then paste same text it works.

Barancev, your screen capture indicates that you are using net35 where as jhone is using
net40

And please explain what do you mean by "click does not work" -- do you have any error
messages?

No error message. The script comes back as if the button has been clicked. 
In some pages (not google) I can work round by sending a new line character to click
a button or a space to select a radio button.

Well, you have to create a convincing sample :)
I can't reproduce the issue following your directions.
