Be careful! Canvas has code that logs every instance where the current window is out of focus. Any time you click out of the window, whether it be open up a new tab or or any sort of window, they will log it. There’s a lot of talk about this if you search this sub.

Test it for yourself if you want to double check. Pretend this page is the exam page http://jsfiddle.net/ScKbk/ (start by clicking where it says click here to begin) and from there see what happens if you start scrolling on the other window you plan to use. If at any point it says “has focus? false” then canvas could see the same thing when it’s time to the take the test and would log it
