Help, please, with a beforeQuit script

Question

The script uses a beforeQuit event handler to copy InDesign libraries from one folder to another. Some of the libraries are large and the process takes a while.
I would like to display a progress bar so that users know that their PCs haven't frozen up. But it only flashes into view briefly. Then the InDesign window closes, but the file-copying is still taking place.
Is there some way to delay the actual quit event until the beforeQuit function has finished? Or maybe what I need is a way to display the progress bar that isn't dependent on InDesign.

Hi Robert
You can use vb and applescript
To display a simple alert that won't close on the application quite is quite simple.
Note the use of the 3 quote marks.
A progress bar is more complicated.
myVBScript = '''MsgBox "Hello there",64,"My message Box"''';
myAppleScript = """tell application "System Events" to display notification "Hi there!" with title "Greetings" """;
// if the above notifcation doesn't work i.e. old o.s. then you can do the below alert
// myAppleScript = """tell application "System Events" to display alert "Hi there!" """;
if ($.os.match(/^W/)) app.doScript(myVBScript,ScriptLanguage.VISUAL_BASIC);
else app.doScript(myAppleScript,ScriptLanguage.APPLESCRIPT_LANGUAGE);
