Hi Fatenah
Basically, a button is present in order to carry out an
action once clicked. So the line between the "Active" and
"Inactive" parts represents the stopping point were it pauses the
movie. I think the Inactive bit is simply indicating that if the
slide were perhaps 10 seconds long and the button displayed the
whole time, but paused at 5 seconds and was programmed to
"Continue", then the user would see the button, but could not click
it for the remaining 5 seconds.
Does this help? Rick
