Why is my "Use Portion of Background Image" option missing?
I have Cap 8 running on a Mac. I opened a new Responsive Project and selected one of the standard themes but when I look ate the tablet or mobile views, the backgrounds scale down and get distorted. the help says there should be a "Use Portion of Background Image" check box in the properties panel (just about the "Master Slide objects on Top" box) but I do not have one. Any ideas why it is missing?
