Thanks for the quick reply, I tried it as below, but still no joy i'm afraid.
This is the relevant code from DrawNode:
Element nodeElmt =
m_objSVGDoc.createElementNS(m_objSVGDoc.getNamespaceURI(), "rect");
nodeElmt.setAttributeNS(m_objSVGDoc.getNamespaceURI(), "x", m_strX);
nodeElmt.setAttributeNS(m_objSVGDoc.getNamespaceURI(), "y", m_strY);
nodeElmt.setAttributeNS(m_objSVGDoc.getNamespaceURI(), "width",
"40");
nodeElmt.setAttributeNS(m_objSVGDoc.getNamespaceURI(), "height",
"40");
nodeElmt.setAttributeNS(m_objSVGDoc.getNamespaceURI(), "style",
"stroke:black; fill:white;");
registerListeners(nodeElmt);
m_objSVGRoot.appendChild(nodeElmt);
array[0] = nodeElmt;
Element txtElmt =
m_objSVGDoc.createElementNS(m_objSVGDoc.getNamespaceURI(), "text");
Text value = m_objSVGDoc.createTextNode(m_strName);
txtElmt.setAttributeNS(m_objSVGDoc.getNamespaceURI(), "x", m_strX);
txtElmt.setAttributeNS(m_objSVGDoc.getNamespaceURI(), "y", m_strY);
txtElmt.setAttributeNS(m_objSVGDoc.getNamespaceURI(), "dx", "2");
txtElmt.setAttributeNS(m_objSVGDoc.getNamespaceURI(), "dy", "20");
txtElmt.setAttributeNS(m_objSVGDoc.getNamespaceURI(), "textLength",
"36" );
txtElmt.setAttributeNS(m_objSVGDoc.getNamespaceURI(),
"lengthAdjust", "spacingAndGlyphs" );
txtElmt.setAttributeNS(m_objSVGDoc.getNamespaceURI(), "style",
"fill:black");
txtElmt.appendChild(value);
m_objSVGRoot.appendChild(txtElmt);
registerListeners(txtElmt);
array[1] = txtElmt;
Is there something I should be doing when initialising the applet, or some
special way the canvas has to be added to a swing component. I'm really at a
loss.

I suspect the problem is in your DrawNode code. In particular I
suspect that you are using 'createElement' instead of 'createElementNS'
with the SVG_NAMESPACE_URI for the namespace. It would produce
exactly this sort of problem.

The above repaint is not useful and could be harmful. I suggest
you remove it. The Canvas will repaint as needed.
