Processing works fine in an empty sketch, but the moment I use ctrl-o or any other way to open a file, the gui doesn’t show any of the textfiles, and when you then press cancel processing crashes with the following message:
Exception in thread "Thread-7" java.lang.NullPointerException

I have already tried changing redownloading processing after deleting the processing folder, sketchbook folder and .processing folder.
