Due to recent security warnings for Java, Oracle recommends downloading the latest update from java.com, which fixes these problems. Some experts have recommended disabling the Java browser plug-in. Disabling the browser plug-in (instructions here ) will not interfere with FileMaker plug-ins from 360Works, although completely uninstalling Java will prevent 360Works plug-ins from loading. If you are using SuperContainer, consult the SuperContainer documentation before disabling the Java browser plug-in.
