Advance with dialog question

[Sheldon Skidmore]

Hello Fellow WF'ers,
 
I have a workflow in which a user executes a workitem and performs a
transaction, then some background tasks occur, then (based on background
results) a specific user decision is displayed.  For some reason the user is
getting popped back into their inbox to execute the user decision - instead of
it executing immediately.  I did some checking and all the 'Advance with Dialog'
flags are turned on.  Also, each dialog task is determined via a SAP office
distribution list (the same list for both tasks).
 
I have similar scenarios in the same workflow and do not run into this issue.
Any ideas on why they are getting put back into their inbox and forced to
execute the item manually?
 
Thanks,
Sheldon Skidmore
