I'm completely new to Processing.  I downloaded the file processing-2.0.1-windows32.zip using Windows XP, extracted it, and clicked on Porcessing.exe.  A splash screen appears, and that's all.  When I double click on a .pde file, the same thing happens.  I followed the directions in troubleshooting, and tried to run Processing from a Cmd window with the --l4j-debug option, and generated the following log file, but the same thing happens: a splash screen, then nothing.  I've tried deleting the extracted folder processing-2.0.1, re-downloading, and re-extracting, but the same thing.  Any suggestions?
