This used to work fine until a week or so ago, and I am not sure what has changed since then. I have just uninstalled what seems to be all the JVM stuff on my machine and reinstalled with the latest recommended Java version from java.com (1.6, update 23). The plugin works fine in IE and Firefox, but in Chrome it fails and the pages that try to use the plugin act as if Java is not installed. I have tried this in both Chrome 8 and Chrome 9 with the same result.

How can I diagnose and fix this?
