When a project is opened (and later when the ProViewer is created) ProView automatically opens a page. The default is the first page in the page list. This can be changed by choosing Project Info under the File menu. The project info dialog will appear. There is a pop-up menu that allows you to choose the page to be opened first.
Selecting “First Page” (the default) will always open the first page under the Contents menu. If you select a page title, that page will always be opened automatically regardless of the page order, even if you change the pages name. If “none” is selected, only the menu bar will appear when the project is opened.
