Hi Neil, I have the 32-bit version installed on my Win7 machine at home, too. I was able to reproduce my own problem here as well.
When I run your example, the first plot looks like I'd expect. The second one does not have the circle. If I remove the \circ from the text-extent it doesn't change anything. If I remove \circ from the text-extent and the draw-text, then the circle appears. If I remove \circ from only draw-text (leaving it in text-extent), the circle also appears. I did take a screenshot if you want to see it. Otherwise, the numbers are 39.0 13.5 2.5 0.0 31.0 13.5 2.5 0.0 I then uninstalled the 32-bit version, downloaded and installed the x86_64 version, and reran your example. The same thing happened again. Something maybe helpful: when the \circ is in the string for draw-text the text is NOT rotated 90 degrees counter-clockwise. When the \circ is removed, the text is drawn rotated 90 degrees counter-clockwise. ...Ah, I see Kieron has uploaded an image to show. That is exactly what I see.
