Interactive Flat PanelsBlank Screen on Flipchart/ Page Browser shows everything.

Hi Jay, 
Unfortunately this usually means the flipchart has gone corrupt/not saved correctly and only the preview of what the pages looked like remains. 
Are you trying to open it from the computer that it was created on? If not, this sometimes resolves the issue as ActivInspire is able to retrieve the content from the temp folders.
