Looks like they fixed a bug in v7:

The correct format for the points property is that each point is a 
comma-separated pair, with each pair separated by CR.

Apparently older versions allowed multiple points on a single 
comma-delimited line.

If you change this:
     set the points of grc id tID to x,y,x1,y1

..to this:
     set the points of grc id tID to x,y &cr& x1,y1

..it works fine.
