I have (for all intents and purposes) a blank slide in Powerpoint. I used the Articulate web object insert option and linked to a video on vimeo. Then I used the Articulate attachment insert option and linked to a PDF file stored on my LMS hosting site. When I preview or publish the slide, then click on the Attachment tab, the drop down shows up behind the video player. How do I get the dropdown to show on top of the video player (vimeo) and not behind it.
