Every time I run xpdf, I get messages of the form Error (21103): Couldn't open temporary file '' on stderr, and xpdf just shows me a blank page. It does allow me to change pages (using the right-arrow/left-arrow buttons at the bottom), but I get a new error and another blank page each time I do so. I've tried this on a number of different pdf files, all of which are read without any trouble by gv. Any ideas? --jbf
