	No such luck on this one!  Standard File DOES NOT use the List Manager,
as it has been around MUCH longer than the LM and as such does it's own lists -
which are SINGLE SELECTION ONLY!
	If you need to have the user select multiple files, then you can do one
of two things (or both for that matter??):
1) Write your own StandardFile replacement.  Other products have done it to
solve this problem, and if you then replease it into the  public domain, maybe
more application willl adopt it for SF replacment.
2) Do a hack like what Stuffit does by keeping StandardFile up, but keeping a
list in the background of each file as it is selected and then waiting till
the user clicks on a 'done' button before working on all of the selected files.
(it's still one at a time selection, but you 'batch' them up)
