I want to answer, "What is this 'save' you speak of?" -- LOL. I'm used to apps that just save stuff as you type it in. Having to hit "save" is so 1990s.
I had BeerSmith open, I can see "My Recipes" and "BeerSmith 3 Samples" in the navigation area on the left. Click "Add Recipe", fill out the recipe, close the program. Any modern application will automatically save at that point OR tell you that you have unsaved changes. Nope.
Open the program, repeat the steps, except this time, click the disk icon button. Works.
