Macro to convert glue-to-geometry to dynamic-glue

[Paul]

I'm modifying a graph drown with ovals (nodes with text inside) and
interconnecting lines. I'm converting the line connections from glue-
to-geometry to dynamic-glue (basically, glued to the centre of the
node). That way, I can drag nodes around without the interconnects
being stuck at pathologically bad points on the edge of the node. (A
trade-off is that the interconnects have to be behind the nodes so as
not to obscure the nodes' text, which means arrowheads are not
visible).

I thought I could cobble together a macro to convert all glue-to-
geometry connections into dynamic-glue connections. I recorded a
macro for one such conversion and looked at. Incomprehensible is all
I can say (but that may have much to do with the fact that I don't
know VBA). I'm wondering if such a macro is available on the web?

Actually, this wasn't really such a hot idea. With the arrow heads
obstructed, it is hard to tell at a glance whether an interconnecting
line actually starts/terminates on a particular node or merely passes
behind it.
