In one of my Selenium test cases, I have the problem that there are MouseOver effects that I don\'t want to have. This is what I do:
As Andrew is right. If it is not happening manually then it should not happened here as well.
You can also try to click using JavascriptExecutor
WebElement element= driver.findElement(By.xpath("Your Xpath"));
JavascriptExecutor executor = (JavascriptExecutor) driver;
executor.executeScript("arguments[0].click();", element);
Below is some example that how you can do it using C#
Execute JavaScript using Selenium WebDriver in C#
Hope it will help you :)
