I don't understand why this happens:

I get a message from Subscriber1:
- I read the message and click Reply. The new message is addressed to: 
Small Cell Lung Cancer
- I read the message and click Reply All. The new message is addressed 
to: Small Cell Lung Cancer; [log in to unmask]

I get a message from Subscriber2:
- I read the message and click Reply. The new message is addressed to: 
Subscriber2
- I read the message and click Reply All. The new message is addressed 
to: Subscriber2; [log in to unmask]

Why the different results? Configuration is set: Reply-to= 
List,Respect

What I think should happen is:
- I read the message and click Reply. The new message is addressed to: 
Small Cell Lung Cancer (or [log in to unmask])
- I read the message and click Reply All. The new message is addressed 
to: Sunbscriber; [log in to unmask]


What else besides Reply-to in the configuration determines who reply 
messages are addressed to? Any wisom or WAGs appreciated.

Thanks,
