sequence of messages of stack vs. standalone

[Douglas Ivers]

What are the first several messages sent when a stack is opened in Rev?
What are the first several messages sent when a stack is opened as a  
standalone?
By "first several messages," I mean all the messages up to the first  
idle message (in a simple stack) or at least to the first openCard  
message.

I'm getting a difference in behavior between the stack and the  
standalone that I don't understand.  In other cases, I see a  
difference in behavior between the first time I open a standalone and  
subsequent openings.  I don't think this happened in Rev 2.6.
