Print Preview in Print Layout Stopped Working X17

[PitMan71]

Any idea what would cause the preview panel to stop working in the Print Layout DBX in X17? I have tried restarting CA, restarting computer, changing sheet sizes and printers for PDF but nothing is working to restore it. I have seen threads on this before but I can't find them.

 

Thanks in advance.

Nevermind. I found the issue. Radio box at the bottom somehow got unchecked. "Update Automatically".
