I operate in tabs. I have my account page in the first tab and the Paid-to-click page in the next. Just click thru a few of the pages there and I have the forth, and last, page be the sudoku page and I just complete a game of that (usually takes up enough time).
Once I'm done with that game I click on the ad (which opens in a new tab) and it updates the progress section saying I've clicked on the ad and then close the tab which opened for the ad.
Then I click the toolbar link to go to the toolbar page (which opens in a new tab). Once the progress section shows that I've done that I close the toolbar page.
Finally, I click the "Click to get your credit" link which tells me to leave the next page open for 60 seconds. I click that and coolsurveys, or w/e, opens in a new tab. I then either complete another game of sudoku (on the Paid-to-click tab) or just let it sit on the account tab and do something else for a minute.
I then refresh the account tab to see if I've gotten the credit...if not then I leave the tabs open (there are 3 at this point) for a bit more and then refresh the account tab again. By this time the credit is showing on my account and I close the 2nd and 3rd tabs (the Paid-to-Click tab and coolsurveys tab).
I've done this for a few days now and have had no problems what-so-ever. In addition to getting $.15 I'm also doing myself some good by completing the sudoku puzzles (stimulates the brain...or something, lol).
I use Firefox for this by the way. When clicking the links it automatically opens in a new tab. Not sure if I had to change a setting to get it to do this...but it works for me!
P.S. If I've misspelled something or put something in the wrong order then I'm sorry. I complete these things when I first get up and I'm about to go to bed so I typed all this from a tired memory, lol.
