SL2 - Temporarily Disable Next button first visit, enable for second visit
For my projects the client requires the learner to listen to all audio on the slide before continuing. In SL 1 I had to do this with conditions and variables. I was happy to see it could be done with triggers in SL2, see article, http://www.articulate.com/support/storyline-2/how-to-temporarily-disable-or-hide-navigation-buttons
This works perfect the first time through. The problem is when the user returns to the slide, the next button is once again disabled.
I know my client will want the slide to work as it did with the variables method in SL1, where once a user completed a slide it then remained unlocked if the user returned.
Is there a way to get this effect in SL2 with the new trigger method?
