Unfortunately, it became corrupt and new versions are no longer available. But it did save all the text in separate text files.
The good news is that I found a couple of new notepad widgets. Both have their good and bad points.
The best one for me is SecretNotePadPlus. It allows for extensive editing and has a large window if needed. It can also lock the notepad with a password as shown in the bottom screen shot below.

The other one has a fixed window which is much smaller. Although it doesn't have the same edit capabilities, it does have the facility to enter a category if you use multiple windows and also a page title. Both of these are lacking in SecretNotePadPlus.
Below are a couple of other screen shots.
