Webmin - Sendmail start button not working

[Usagi]

My system:
Fedora core 4
Sendmail 8.13.7
Webmin 1.360

Sendmail is running but the button on the sendmail page reads "Start" When I click it it still says "Start." I can remember in the past that it would say "Stop" after it was pressed.

Basicaly this means I can't stop sendmail using webmin.

If I use ssh and enter:
/etc/rc.d/init.d/sendmail stop
I get:
Shutting down sm-client: [ OK ]
Shutting down sendmail: [ OK ]

/etc/rc.d/init.d/sendmail start gets:
Starting sendmail: [ OK ]
Starting sm-client: [ OK ]

So it appears that sendmail is stopping and starting if I use ssh. Why doesn't webmin's start/stop work?

Thanks
Usagi
