After few seconds, I found a way to overcome it. Rather than repeating do right click, which repeatedly un-selected the text, i pressed the option button on the keyboard, the on between the 'Windows' and the 'Control' button, in the last row on Windows PC,,, yes that one with the space bar.
It worked. pressing the option button actually presented the disabled right click options. and then i used the option of google search with the mouse click.!
You can try it Mac as well..
