Tag, thank you very much for the quick response. I am also still having the same problem as chiss described. My machine is a Dell Pentium M Chip, 2.0 GHz, 2 GB RAM laptop.
I also noticed that the new version somehow does not use the USGS Digital Orth graphics data and high res LandSat data. I can prvoide screen shot of wwj0.3.0 and wwj0.4.1 using the same dataset if you think that helps.
