Sentry is a secure desktop environment that password protects your
style. It expands on the basic Windows "lock" function by offering complete
screen layout control.

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.
