Click is working but it throws error org.openqa.selenium.ElementNotVisibleException: Element is not currently visible
<p>I have used cssselector, xpath and linktext for clicking a drop-down list item and all works fine and it clicks the element however the exception ElementNotVisibleException is thrown at the same time! There is no duplicate element also in the DOM.</p>

<p>I was using selenium-server-standalone-2.45.0 and also tried updating it to 2.48.2 but the error is still there. 
Tried it on both firefox and chrome but results the same. Any ideas?</p>
