SwitchList train assignment may not always be predictable.

Whenever a user switches from the overview tab to another tab and back, train 
assignment is repeated.  The assignment code should be repeatable - it should 
give the same answer each time.  If not, then it's possible for the train list 
to change between when the switchlist is printed and when the train is marked 
completed.

It looks like there might be cases where the assignments aren't predictable.  
From John Houghton:

"An interesting observation with Switchlist and Lion. During the testing of the 
lists, I would create new Desktop spaces so that I could have Safari, 
Switchlist and TextWrangler open in their own spaces and slide between them 
all. I noticed that sometimes from the overview tab in Switchlist, it would 
show me different numbers of cars to move on the different trains I have. If 
Switchlist was open on the home desktop, the overview list would be correct. If 
switchlist was open in a secondary space, sometimes one of the trains would 
report 1 less car to move."

This ought to be diagnosed and fixed.
