it stays switched off after loading a new file.
It further can override the PageMode defined in the PDF:
COMPDF_EnableNavigationAfterLoad = 616:

1: AsDefinedInDefaultPageMode - always use COMPDF_SetPageModeDefault
2: DefinedInPDFOrDefault - reset navigation after loading a new file
Delphi Example:
Display the thumbnails from the beginning (after loading a PDF file)
FViewer := TWPViewPDF.Create(Parent); // Parent can be a TPanel for example
FViewer.Parent := Parent;
FViewer.ViewControls := [ wpViewLeftPanel, wpViewPanel, wpVertScrollBar, wpHorzScrollBar ];
FViewer.ViewOptions := [ wpViewThumbnails ];
FViewer.PageModeDefault := wpPageModeThumbnails;
FViewer.SetBounds(1,1,Parent.Width-2,Parent.Height-2);
