- From the station log, choose Request → Screenshot to see exactly what's on every display the station drives.
- Use Identify this station to make it flash on screen. If the flash appears, the app is running and drawing.
- Use Restart app, which fixes most frozen-app cases in seconds.
- If that doesn't help, use Reboot station. This takes the kiosk offline for a couple of minutes.
You can also open remote desktop to look at and control the machine directly.
