is not working on/with Clozure CL-x8664 (Welcome to Clozure Common
Lisp Version 1.3-r12149M  (DarwinX8664) !)
no position or size of any window, listener or editor is restored to
the position or size you are have save/close the window or quit the

good example for getting back were you have left it off is VisualWorks.
most of the time my work is 'in progress', hardly ever completed.
returning to you work were you left off is essential in my mind.
it is essay to star new one then restore each time the previous one
which may include many files, ref docs etc... the productivity and
piece of mind is apparent.

we are talking about a preferences option - and useful option too.

if we take all possibile scenarios in account (and we often try to do
that - i do and fall many times :-) ) we never would finish or make
any useful/time essential decisions.
i think many of use - i assume - would welcome this functionally.
