When I try to use "Get .zip" button in the Playground I the dialog to save the file does not appear when using it with code that is using Canvas2D.
In Screenshot from 2016-12-12 10-31-21.png you can see in the lower left corner it says "Creating archive...Please wait".
If I comment out the call to create(scene) as can be seen in Screenshot from 2016-12-12 10-33-15.png you can see the I'm allowed to save the zip file.
I've only seen this on projects using Canvas2D but maybe its unrelated to Canvas2D.
