I have the same problem with all of my S10 Wyse terminals after upgrading from WTOS version 6.5.0_30 to version 7.1_033. The power button restarts the terminal instead of shutting it down. Any help you could provide would be greatly appreciated. I am using the following wnos.ini via a DHCP designated FTP server.
Fixed! My this problem appears to be related to upgrading from WTOS 6.5.0_30 to WTOS 7.1_033. I was able to fix it by downgrading to WTOS 7.0.1_13. It was at this point that the power button worked correctly. I was then able to upgrade to WTOS 7.1_033 and the power button continues to work correctly.
