           Summary: Error with kepler20080122.zip version (PTII?)
           Product: Kepler
           Version: 1.0.0beta3
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: general

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?
