First I placed a background box with a rollover color. On this background I placed a panorama (basic slideshow/widget). The rollover does not work when dragging the mouse from the top on the panorama images. How to correct that? The rollover works well with frames of simple images or text blocks.
This works fine here! Could you please create a small(!) .muse document, using only the standard slideshow with standard images and the background box and give us this .muse file, tom have a look at? Please follow this instructions: https://forums.adobe.com/docs/DOC-8652
You should use the state button instead of a rectangle in order to achieve what you want
