This may sound like a stupid question, but I'm paranoid and am looking for an answer. What happens to an application if I leave it (not kill it), while it is finishing an operation (the spinning circle in the upper left corner)? Does it finish that operation? or does it stop what it is doing. Let's say, mail is checking for mail and you leave the application while it's checking. Or a page is reloading? stuff like that. Thanks in advance.
