Is it possible to control that when i launch a perspective session , It launches in new chrome browser window.
Now , when I am launching a window ,it open a existing chrome window and just open a new tab beside it.
Thanks a lot for the replies 
I don't think you will be able to force that option with Ignition.
But, Chrome has this built in by 'Shift'+click on the links to open a new window. (Ctrl+click or middle click for new tab)
