html5 links in Blackboard 9.1.

Hi again!

We are currently using Storyline in our Blackboard 9.1 courses. When I attempt to include the link to our published Storyline file as a menu item or an embedded link, the file does not open. It gets stuck loading the content. When I select "Open in new window" it works fine. Will the Storyline file only open in Blackboard if we use an external URL that opens in a new window?

Thank you!
