I'm assuming the data isn't saved properly when you do the above. Is  
that right?

One possible problem is the following two lines:

    set the custompropertyset of stack whichFile to "allDataProps"
    set the customproperties["allDataProps"] of stack whichFile  
to ......

I don't think you need the first line, and it could be the cause of  
the problem (just guessing). The syntax of the second line (set the  
customproperties["allDataProps"]) is a way of addressing a custom  
property set without needing to specifically set it. The following  
are equivalnet:

1.    set the customproperties["allDataProps"] of stack whichFile  
to ......

2.    set the custompropertyset of stack whichFile to "allDataProps"
        set the customproperties of stack whichFile to ......

Cheers
