I am facing an issue in Google Chrome, when I am trying to add bookmark it is allowing for the first time but when I am trying again Screen is getting darker but no bookmark pop up window is appearing, when I am clicking again on add bookmark, it is getting darker and finally its getting black. I have tried clearing cache, cookies and temporary files and cookies, then it is allowing for the first time only after that same issue repeats. Has anyone faced this before?? Any solution for this??
