Hi Patrick,
Things have changed a bit since I started using STUDY, but the basic
problem is the same. I watched the program more carefully. It is
drawing a few hundred lines, and setting their stroke property. It
draws many of them, and then suddenly it just craps out and gives a
bizarre error:
Method setStroke for class edu.umd.cs.piccolo.nodes.PPath with
signature (java.awt.Stroke) not found at (eval 9) line 1228
at ./p3.pl line 45
Here is one of the setStroke() calls that succeeds:

Everything seems fine, but suddenly java sends back an error packet.
I can change other bits of the code and generate similar errors. It
seems that something is going wrong deep down.
Cheers,
