Hi Justin,
I came across an issue with the way 3D flip cards are reacting with slide out menu depending on the size of the window being used. Sometimes the menu is in front and sometimes the card is in front. I have been using these features together for months now with the flip book output and never had this issue until now. The first image is when in full screen, the second is when the window is sized to about 3/4 of the screen. The menu does not behave this way on any other pages except for the ones where a 3D flip card is used.
