Does anyone know why Reader X doesn't show the "Some Features Have Been Disabled..." prompt when you're on a page with an embedded video? Is there some sort of pop-up or prompt blocker? I understand you need to select the "always trust" option, but it's not showing up, and going through the preferences -> multimedia trust options seems to be purely cosmetic (i.e., no results). Interestingly, the prompt appears on my Mac, but unfortunately the customer who bought our interactive PDF is on a PC and doesn't see the pop-up. Thanks for any insights.
