Hi Leon,
Yes, this is expected behavior. There may be times where a page change is invisble to the learner (such as some software simulations or quizzes). We'll see about adding a lesson setting so that this can be configureable.
In the meantime, there's a workaround that you can use.
- On the Master Page add a text object to the top left corner,
- make the text white, or the same color as your background to "hide" it (keep Start Visible = true),
- turn off the Show Focus Ring property on the text object.
- Create an action that says onPageChange > Focus on (text object). The "Focus on" block is under the "Page" category.
See attached image. That should force the page to scroll back to the top any time the page is changed.
Let us know if that doesn't work for you!
