I'm glad it's working now, and your PGF/TikZ illustrations are beautiful!
Perhaps I should remark that I'm not _advocating_ the use of PostScript specials. It's simply that I have mundane reasons for using them, currently. The first version of Watch was written for my own use, so I made it work with the documents that I'm writing. Since then, I've tried to make it more generally useful, hence PDF being the default mode in the current version.
I look forward to the day when I never need to use another PostScript special, and I can do everything with PDFLaTeX.
