When loading a PDF file, how can I view other pages than the first one? There is no next page button.

In which program?

In XnConvert it is possible to step through the pages of a multi-page file using the arrow keys in the preview window, in XnView Classic and XnView MP use the small arrows on the toolbar...

In XnConvert (this is XnConvert forum right).
The keyboard arrow keys doesn't do anything for the PDF. The small arrow buttons flip through PDF files not the same PDF file pages. Not even page up or down work. I have XnConvert version 1.76
