Opaque dialog to confirm credentials and signout button does not work ...

Zoho Team,
 
I normally have Zoho Writer and Zoho Sheet open in two different browser windows. When I signout of Zoho Sheet, and after a while, when I get the opaque dialog in Zoho Writer for the following actions (reconfirm password or Signout completely).
 
But none of these options work and the links are dead.
 
Can some one look into it?
