As an experiment to see what an AS template does, or does not do, I created one. It did NOT do what I wanted, so I deleted all of the parts of the template, as far as I have been able to determine. I THOUGHT everything was OK at that point.
Just now, I opened AS, intending to create a new project. In the list of project types in the middle of the New Project window, there is an entry for that template that I do not want.
How can I get rid of it? I could find almost nothing in AS Help about Project Templates.
