Disabled NEXT button does not return to normal if user goes BACK
I've got a slide 2 with 3 objects and all 3 need to be clicked in order to advance to the next slide.
I've created a trigger to disabled the NEXT button when timeline reaches 0 and a trigger to set it to normal when state of all 3 objects is visited.
I've set the slide 2 settings to "resume to saved state when revisiting" because I don't want the user to repeat the task.
On slide 2, the NEXT button gets activated after clicking the 3 objects and the user can go to slide 3. However, if the user clicks BACK from slide 3, he finds himself back on slide 2, but the NEXT button is now deactivated, even if the states of the 3 objects remains visited.
The only option I could find to make the NEXT button work was to set the slide options to "resume to initial state when revisiting". But this is an inconvenience because the user should not be required to complete the task again but only review the visited objects.
Does anybody know the solution for this issue?
