Bernd,
reading your fine site I couldn't figure out the additional feature I would gain if I switch to the pro edition of Objective Basic. The IDE says it would include a deploy option. Will there be a choice to target 64Bit as well?
BTW: What feature makes the resulting code so special it only runs on Snow Leopard? Wouldn't it be possible to a least target Leopard as there still is a large installed base out there. I could imagine that you don't have the resources to test in several environments at once, but it would extend the target audience for Objective-Basic (for you) and the resulting applications (for us).
Kind regards
Udo
