I've experienced something similar to this, in which spacing bewteen words is irregular, with some being run together and others not. It only occurs on my web pages. I have never figured out what the cause is. Note that I do not use PAF to generate my webpages, though. Instead, I use GedHTree, a freeware Gedcom translator that creates HTML pages from a Gedcom file. It's rather limited, in that it doesn't support all of PAF's features (media files, for example), but it's free.
