This is a simple scenario that I'm trying to get working in Acrobat Pro.
I've create a basic layout in InDesign containing a circular image on layer 1. Layer 2 contains a caption box explaining the image in the circle.
In Acrobat Pro, using the Forum Button Too, I drew an outline around the circle on layer 1. Initially, layer 2 is off, but when the mouse enters the button, layer 2 (the caption box) is revealed. But I want layer 2 to stay visible, because there's a hyperlink in the caption text that I may want to click on. Otherwise, I want the caption layer to time out and disappear on its own after a few seconds, because I don't want it to stick around and clutter my document in case I create another button on layer 1 that reveals a different caption box on a different layer, and so on.
I think I figured this out. The solution is to set the layer visibility for each button to show ONLY the layer for the caption box associated for that button. Then if I mouse over another button, it will take precedent by making visible only its associated layer, thereby making all other layers invisible. Unless all the buttons I intend to include are crowded together, this should work perfectly.
