[Dillo-dev] FLTK 1.3 and current development version

I have some trouble using Dillo 1.3. When I click on the "Book" icon, select "view page source" from the menu or try to load a page from disk I get the message: "ERROR: can't start dpid daemon (URL scheme='dpi') or 'file' What could be a possible cause for this problem? Where in the code does it try to start this daemon? Georg
