I've discovered that an MPW tool cannot initiate an AppleScript more than once. The
problem is that the AppleScript subsystem maintains some per-process information in
it's cache, and expects that process to stick around until an ExitToShell. Since an
MPW tool behaves more like a plug-in, it doesn't call ExitToShell, and so AppleScript
doesn't notice when the code fragment that called it goes away. When it's called again
from the same Process Manager process, but a different context within that process, it
gets horribly confused as evidenced by the crash.
I could find no solution to this problem for the MPW tool environment. My solution was
to add a RunApplescript built-in command in the MPW Shell. That command is available
in the latest version of the shell, 3.6d4.
