Thanks, a write up would be appreciated, but it looks pretty easy. I've got the two files up in Inkscape and (other than the fact Inkscape has lost the left side and top lines on your file, fritzing seems to find it fine) it looks like I just needed to add a circle without connector ids at the appropriate grid points. If there is an easier way than manually editing the xml I'm all for it thought. Every piece of software I've ever used has idiosyncrasies but at least with open source if you care enough you can fix them and fritzing is doing an awesome job. I hope the various companies that are using fritzing for their tutorials are also providing funding (as there seem to be a lot of them ...).
