Yes, a timer can do the job.

- Create a public property, say oApp.lActivity
- Create a timer that fire every 5 minutes
- In the Timer event, check the status of the oApp.lActivity property:
   - .F.: Log out
   - .T.: Set it to .F.
- In every control, set oApp.lActivity to .T. everytime the user type or click something (in the InteractiveChange(), Click(), etc.)
