I have found this 'trick', to do my 25 clickgrid clicks just a bit faster. After clicking a grid cell, I don't click the close button. Instead, I look at my browser's address bar. This bar contains 2 numbers, these are the co-ordinates of the cell you've just clicked. If you change one of these numbers, and hit enter, you're visiting the website at that cell as if you clicked it.
This is not a hack, you're not cheating, or even taking money away from clicksense, the only thing you're doing is saving the effort of lclosing and re-opening the page.
