Can you give us some more informations: - It seems the client has a dual-core / dual-cpu / hyperthreading machine - is your one equally equipped? - Do you both have the same OS and Java version? - Did you use the same large shapefiles for your local tests? As the CPU usage seems to be 50% (of 2 cpus) in both cases, I think that there's one thread using all CPU it gets, trying to render the shapefile, and thus blocking the window updates. I've seen screen update times of nearly a minute for complex shapefiles. > (see attached screenshot) A little (off-topic) remark: Please don't send such large .bmp files to mailing lists, it was about 3MB large, which grew to 4 MB to the base64 encoding used in email. Converting the image to .png format reduces its size to 100kb (factor 30), without any loss of quality. Thanks, Markus -- Markus Schaber | Logical Tracking&Tracing International AG Dipl.
