Resuming from dormant

If, during play back of a movie, I press e.g. the search button and then back again to the player page, the page is blank and doesn't respond to any input.
If I put a break point I can see the message "Resuming" on the page, as if the player is trying to resume play back.
Should the player be able to resume play back by itself or is it something you have to do to make it work?
