WBOs in Storyline (Intranet vs. Internet)

Hello Articulate friends -

I have a course that I would like to have a WBO on a slide that is a pdf that's accessible from our Intranet site.

I've tested out WBOs with IntErnet sites and they work just fine when I access the course from our LMS; however, now that I'm using an IntrAnet site, when the page loads in LMS, it gives a message that says "Only secure content is displayed." When I click the button to Show All Content it kicks me out of the course.

UPDATE: When I have the WBO display in a new browser window it works just fine. It's only when it's set to display in slide that it doesn't work. However, it doesn't serve the purpose I want it to if it doesn't display within the slide.

Any ideas what may be causing this? I'm nearly positive that I got one of these pages to work when we originally tried the Storyline demo out, so I'm not sure what I'm going differently. I realize that this may be an issue either on the LMS side or with our Intranet, but thought I'd start here.

Any ideas or input would be much appreciated!

Thanks,

Tessa
