As I'm sure you're all painfully aware, I'm an absolute beginner with AS
(any kind of programing/scripting for that matter), so please bear with me,
and I apologize if this is an annoyingly stupid question. I've just been
fiddling around in Script Editor (I'm still in the poking around and
exploring stage of AS self-tutoring) and I stumbled upon a behavior that I
found a little confusing. Perhaps someone could illuminate this for me.
If I enter this into a Script Editor window and run it:
display dialog "Pointless!" giving up after 3
quit
I get an error saying "couldn't run script because a script is running". I
assume that this means that the quit command was directed to Script Editor
which couldn't fulfill the request because it was busy running the script
which sent the command. If I save the above script as an application it
behaves how I would expect (it displays the dialog and then quits).
If I save this as an application:
display dialog "Pointless!" giving up after 3
tell application "quitter" to quit
It works just fine, but if I run it from the Script Editor window, the
dialog appears and then goes away after three seconds but the script doesn't
quit and the application menu blinks an alert. Script Editor becomes
unresponsive and I have to command-tab or click on the desktop to switch to
another app. Then I find (not altogether surprisingly) that the "tell"
statement has launched the compiled application "quitter" and then another
"Pointless!" dialog box is displayed. However, I noticed that the dialog box
either didn't show up until I switched to the "quitter" application or the
countdown to giving up didn't begin until I switched to the "quitter"
application. Once "quitter" becomes the active app, it behaves as expected.
However, when I subsequently switch back to Script Editor, the original
script appears to still be running (spinning beachball). Why? And why
wouldn't the launched script application just do its thing quietly in the
background?

PS - I'm on OS 9.2.2 with AS 1.8.3
