Kepler

The nightly zipped version (kepler20080122) ends up having a recurring error shown in the terminal when the cursor is moved over the workflow display area.
The error appears in diva.canvas.BasicZList (see below) when executed using kepler.bat (Windows) or kepler.sh (Mac). Kepler seems to work OK, but error keeps appearing. Does not occur in keplwe20080118 so maybe a recent change in Ptolemy code?
