Good, I had just opened up my code to see what it was doing. The use of stroke twice (once for the color of the stroke and once as id) was simply a convenient way of giving each object a unique id (I assumed the probability of having two 24 bit random integers being the same was negigible). I used the id for figuring out which object to drag, but in this case evt.target could easily have been used for the same purpose. I will simplify my code when I get the chance.
Glad you got it working!
