ankh,
that might be true of certain unnamed Operating Systems that charge you anew for each new version that comes out.... but not for Rick! The bugs that have surfaced in the past were either oversights, typos, or honest mistakes.
Since Rick will continue to be lead developer on this software, and all code will be run by him for QA & Testing (actually, we'll probably still do a lot of the beta testing, which I think is GREAT!), I don't see this ever happening with this product.
