Problem with Simple Database lesson 18 from App_Academy_eBook

Hi David

I don't have the eBook in question (or maybe I do, but don't remember 
where it is :-), - so I'm slightly guessing ...

I guess (or at least hope) that the eBook builds the app - but didn't 
make a standalone from it.

The issue you have run into is that once a standalone is built, the main 
stack cannot be saved - hence "simple database" aps can't save their 
data.   There are various solutions - rather than give a too brief 
answer here, I'll point you to a well-written article about it:-)
