Hello,
I believe the push() method is not working properly. Instead of inserting actual values, it only pushes "". The .capx is here: http://db.tt/VWmS2a3N
Thank you.
LE: The problem seems to occur when the width, height and depth is set to 0 ( zero ) as initial ( which I should in order to avoid empty values on push ).
Does not seem to be browser or OS related.
