Thank you for great software, but
1. User A installs the software, installs yawcam as a service.
2. Reboot. Service starts as expected.
3. User B logs in - service is running.
4. User B logs off - service silently stops.
It is possible to restart the service manually, but logon/logoff of any user reproducibly stops it again.
Windows XP Pro, both A and B are admins, if it can help.
I'm not alone
