Flowing text in shapes is no longer available in CP-versions later than 5.5.
I plan to post some small tips for Captivate 5. This first tip is a less known, but useful new feature: you can put text directly into a closed shape, such as rectangles, ovals and polygons. Moreover the inserted text will automatically adapt to the form of the shape. In previous versions of Captivate this was a tedious process: put a Text Caption on top of the shape, and try to adapt the text by inserting spaces and breaks.
I created a small Captivate-demonstration to show the workflow. Hope you enjoy watching it!
