I have a fla(flash CC 13.1) with several layers if I add a keyframe and swap movie clip it will cause an anomaly were the if a popup box is open, the dynamic text box text will keep old text with new text on top (titles). We used an array to populate the text, and some of the other features are using addChild.

I turned on outline and moved the text box to see if one was behind it. Also if only one keyframe on the class banner layer this does not happen. titles are dynamic text with the instance name txtSlideTitle and if there where two on the same frame it would give me an error.
