[BangPypers] selenium click not working fot some links

[Saju M]

I created a selenium script in python as follows

loc_link = self.driver.find_element_by_id("tbpi")
print "------loc_link-------", loc_link.tag_name, loc_link.text
loc_link.click()

i want to click on link 'More search tools'.
Tsis script printing element name 'a' and text 'More search tools' correctly.
but 'click' operaion not working

check this page http://www.google.com/search?q=smith, you can see the
link "More search tools" at let bottom.

I could click on some other links in the same page !!!!.
