Engage 13 - Transparent background
I have added an engage '13 interaction to my pptx (ppt2013).
As color scheme for this engage interaction I have chosen 'Forest Green'.
However, when I look at the preview via Powerpoint, then there is a blue background.
1. Where does this blue come from? I can't find it in any color scheme (not from the Presenter player, not in the engage interaction)
2. Actually, I don't want any background. I want all to be transparent, so that I see the background of the Powerpoint slide. Setting transparency to 100% in the color settings of Engage interaction doesn't work or is not enough.
