A bug report -- this is strange in that I cannot be the first trying to create a PNN for classification on Windows VISTA...

Steps to produce the error:

  1. File->New file
  2. Choose Machine Learnign Method, type some name, click OK
  3. In next dialog, choose PNN/GRNN, click OK
  4. In the next dialog, put/choose something, anything, click OK, and you'll get the error

BTW, I tried to download the workbench source but the latest I can find is 2.5.3 in Google Code. Tried git, but the tarball has a few dozen java files in the root dir. Is there a better way to get the workbench source code?

Thanks in advance!

Fixed issue in persistor for PNN, works now. Trained basic XOR network with PNN fine.
