Thanks. I didn’t realize there was a transition in the sample when previewing the single page. I should have published. I used Lectora 17.0.6, maybe the transitions changed after that. I usually avoid all transitions whenever possible, too much effort for too little effect 😉
Another thing to learn from: You can test as much as you want on your side, there’s no guarantee it’ll work somewhere else … and I couldn’t count the number of times I pressed F5, to make A7 a negative value which only happens once in a 1,00,0 whiles.
