You can do a nonblocking click by using either one of these:

The Advanced User Interactions API (JavaDocs)

WebElement element = driver.findElement(By.whatever("anything"));
new Actions(driver).click(element).perform();

or JavaScript:

JavascriptExecutor js = (JavascriptExecutor)driver;

WebElement element = driver.findElement(By.whatever("anything"));
js.executeScript("arguments[0].click()", element);
