Click the refresh button (6)
I believe the answer is:
reload
'click the refresh button' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for reload that I've seen before include "Fill (a gun) again" , "Put more bullets in" , "Ordeal (anag.)" , "Encumber again" , "Put in another charge" .)
