Hi Gizmo,

I am the creator of IRCmagic (http://MicrocosmSoftware.com/ircmagic.html).
And I am happy to report that Ircle can and will save properties of loaded
scripts. All you need to do to get Ircle to save properties in a loaded
script is:

1) provide a unload() handler in the loaded script
2) return true as the result of the unload() handler

Like so:

on unload()
return true -- save all properties
end unload

If you do this, Ircle will diligently save all properties in your script
before unloading it. No workaround necessary.

Good work around, but it need not be an application. A script would do just
fine.

You can load a script into another script, set its properties, and tell it
to do things, all without having to create an application. Some of us
fondly refer to these loaded sub-scripts as "script libraries", or "script
plug-ins". If you are interested in pursuing this workaround, say so and I
or someone else on the list will give you a short example.

To solve the "where is app?" problem you might try using the infamous
double-tell method combined with launching the application by relative path
if the application is always in a known location relative to the main
script. But like I said above, none of this is really necessary if all you
want to do is save properties in the main script on unload.
