In general, i think games are either paused while we attend to other parts of our lives ( yes, some of us do actually have lives, or so i have heard anyway) or are advanced enough ( and have such levels of lag) that they are left to run while we eat or sleep or go to school or work.
You can if you run it in a VM. One of the stand-alone flash players might allow this as well, you might have to get a new auth token off the webpage if you wait a while to run it again.
