What to do this this demo:

Prep work

Close all Notepad and WordPad windows on your desktop

First Demo

Run demo.pl

Open Notepad

Watch. It will open the demo.pl file in Notepad and then close the window. This demonstrates the simplest path through the demo.

Second Demo

Open Notepad. Type some random text in the window.

Run demo.pl

It will attempt to open the demo.pl file, but first Notepad will ask if the existing file should be saved. The script will save it to C:\TEMP\Saved.txt.

Third Demo

Repeat the above steps

This demonstrates that the cnfm options to the dialog on saving the stuff to Saved.txt works.

Fourth Demo

Run demo.pl

Open WordPad

This demonstrates the fork - operates on either Notepad or WordPad.

What doesn't work

The demo doesn't deal with an open Notepad that has an existing _file_ open, rather than Untitled.

The demo doesn't display as much flexibility with respect to WordPad
