Re: [MacPerl-Toolbox] Apple events and PSN ... bug?

Note that Matthias' suggestion of pack 'll', 0, $psn worked, though a
modification of that is used in what I posted today to the macperl list.

Hm ... if you can send a PSN, then the AE manager should at least be able
to use the PSN you pass even if it has changed.  One can only hope.  :)

Right.  I wonder if the AE manager uses the same logic that SameProcess
uses to determine what process you are targeting if the PSN has changed?
