lock and unlock seekbar?
I am wondering, if anyone has had any luck creating a variable for the seekbar.
Currently in my course, the seekbar is locked; however the desired behaviour is the seekbar is locked for a users first visit to the page. BUT when a user revisits the page and completes it once, they should be able to revisit it and scrub through, so they can catch up on bits they want to hear again.
Anyone have any creative ideas on how I might accomplish this?
