Argghh!! Never mind even more. I do feel duuuumb for missing another
message which provides a much more efficient approach for ensuring
one has set the global "directory" variable to a particular open
stack's location, by using item and itemDelimiter syntax instead of
"offset".
Here's what I ended up with, which I believe should be fairly
bulletproof (I hope?)
global vgPath
on preOpenStack
put the effective fileName of this stack into vgPath
set the itemDel to "/"
delete the last item of vgPath
set the directory to vgPath
end preOpenStack
And to further explain, the point to all this is to allow someone to
be able to open a stack using a link from a web page, and ensure that
when the stack opens, all graphics, etc. will be correctly referenced
by relative references in that stack's scripts.

David
