3.02 Known Issues

Known issues: If you run a Java applet, such as the International Space Station layout, and are on Java 7 Update 11 or higher, you may experience an issue. If you see a "Security Warning" dialog, and ignore it or hit Cancel, Sentry may not operate correctly on the next run. To avoid this issue, check the box "Do not show this again for this app" and choose Run. This can be fixed by lowering your Java security settings.

 If the layout becomes unresponsive, you can hit the Windows key or use a triple right-click to pull up the Sentry menu, and exit the app.
