I use a file manager with a preview pane. There, the content of any file that is selected (in an explorer-like file list), are displayed. Actually the file manager is called "Dopus".
Regarding the preview of PDF files, I used to get the normal Browser View of PDF-XChange Viewer in that preview pane of Dopus. After upgrading to the latest version of PDF-XChange Viewer (including the PDF thumbnail plugin) however, I get a new, very basic view called "PDF-XChange PDF Preview Provider" inside the preview pane of Dopus:

I'd however rather have the standard browser view back, especially since there I can see the thumbnail or bookmarks pane as well as customize the toolbars I'd like to see. All of this is not possible with that very basic "PDF-XChange PDF Preview Provider".
So, is there a way to switch from the "PDF-XChange PDF Preview Provider" back to the standard browser view (without having to uninstall the PDF-XChange thumbnail plugin)?
Thanks already,
