Yes, it'd be nice if the LyX documentation discussed file-scheme URLs in the material on hyperlinks. file-scheme URLs give many Windows users trouble, especially because some Microsoft software (notably IE and Explorer) have very sloppy rules for handling them. In theory, you could figure out how to write them by reading the URI specification (IETF STD0066, if memory serves), but it wouldn't be easy. Jukka Korpela has a discussion on file-scheme URLs, including some notes about how to use them on Windows, here: http://www.cs.tut.fi/~jkorpela/fileurl.html > Well, the PDF is processed and it works except in Acrobat where > Firefox opens with an empty tab, but I guess that's an Acrobat problem?! This could be the result of the stricter same-domain policy in Mozilla-based browsers, combined with something to do with how Acrobat is invoking Firefox. There's a short comment on that on Jukka's page. There's not much that can be done about it; it's a security measure, so it's supposed to be difficult to circumvent. By the way, you can ignore the bit I wrote above about using "c|" instead of "c:". That's no longer allowed by the current URI specification. A strictly-correct file-scheme URL on Windows would use "c%3a" for the drive letter and colon. -- Michael Wojcik Micro Focus Rhetoric & Writing, Michigan State University
