Business Insight Toolbox/Content Pane Blank

[testing123]

Hi,

I think this is a browser issue, but I can't pinpoint it. We have a Preview and Stable environment. I'm able to access Business Insight and use everything in it just fine from our Stable/production environment. However, when attempting to do so in Preview, a lot of functionality is blank. In particular, the content/toolbox pane is blank. I haven't upgraded my browser or changed any browser settings, and it used to work just fine. I tried adding to trust/local sites with no luck. Anyone have any other suggestions?

Thanks!
James
