No idea why, unless the stack is being opened underneath the current
one.

This is even weirder.

Or underneath the top level stack, which is the proper behavior unless
the substack is a modal dialog or palette.

No explanation for this either, but my guess is that all three of
these problems are related to the fact that messages sent to substacks
pass through the main stack's script. If you've got any handlers in
the main stack script for any standard messages (openCard, openStack,
etc.) this is most likely what's tripping you up.

If the size and positioning is so critical, why use a separate stack
at all instead of just showing a hidden field in the stack you've
already got open?
If you must use a separate stack, generally the easiest way to make
sure it comes up where you want is to handle the preOpenStack handler
in the card script of the substack and set the rect of the stack
there. Even this may not get you what you need on some UNIX systems,
and you'll have to set the decorations property of the stack to empty
if you really want to accurately position it.
