over the years I've gotten into the habit of hitting F9 then F10 every time I input something and move on to the next sections. Finish w-2's F9 F10, Finish 1099-r's F9 F10. it's now something I'm not even aware of anymore, been burned to many times. Plus I have the refund monitor up and I like to watch it change as I input. That's just my way of having fun when they come in asking about how big their refund will be and I'm watching it calculate a balance due.
