Work area has gone blank?

Hi-While working on my module, I must have clicked something that has caused my whole center work area for Lectora to go blank? I still see all of my chapters, pages, images, etc on the left side but the whole area in the middle is blue?Does anyone have any idea what I have checked and how to fix this? I have gone to a team members computer who also has Lectora and their view of my module is correct. Thanks!
