'array' is alphabetically the first module imported in the default 
two-process mode but not in the one-process mode selected by a command 
line '-n'.  To the best of my understanding, the message reported, which 
I found in the code, should only appear in one-process mode.

Seymour reported that he started Idle by right-clicking on the file and 
selecting 'Edit with Idle'. Asking the above question is easier then 
trying to get him to directly determine what command line is associated 
with 'Edit with Idle' on his particular machine.
