Has everything to do with the API’s available on that version and we require newer ones which shipped with Vista & newer
The new release limitation sounds so simple and reasonable, unless you have users (many older) that do not want to leave XP, because it works.
I do understand the need to shed the legacy issues from windows OS. And as long as Xojo does not include exciting new features that all users will want, then I will forgo compiling on the new releases, but still update my subscription. Right now, the difference in capability does not seem to be a factor.
What might change the situation is a flood of new capabilities for Windows owners that might accelerate the the migration. But at 73, I am not sure that I have that many programming years remaining.
