One thing I would do differently is use the layer.xml file rather than doing it like this:
CentralLookup.getDefault().lookup(Configuration.class); I.e., if you use FileUtile.getConfigFile, you'll be able to get a folder in the virtual file system: http://bits.netbeans.org/dev/javadoc/org-openide-filesystems/org/openide/ filesystems/FileUtil.html#getConfigFile-java.lang.String- And then you can enable/disable something there. But, better than discussing this via e-mail back and forth would be for you to put a small app together with the code from your e-mail in a repo on GitHub so that others can take a look at it and suggest alternative approaches. You should also think about whether it is good practice in terms of usability to have a window that appears and disappears automatically -- normally that's not something that you'd want to do programmatically.
