HTML Overlay

Hello!

i'm working on a world where a 3d cube should be displayed. By clicking the cube a HTML-overlay with a slideshow or a video should be displayed.

At the Moment I am able to show the slideshow. (diplay: block) But when i hide it again (display:none) the 3d cube is not visible any more.
When I open the video (hide trackable1, show trackable2) the video plays as expected and snaps to the screen. But when I click the back button the video disappears, but the cube shows not.
Do i have to do more than:
"trackablevideo.enabled = false;
trackable.enabled = true;""

Yesterday it worked with the slideshow. But today it's not showing the cube after I hide the overlay... confusing
