General

I wanted to get more data for this bug:

38576 Framework » Macintosh File types are no longer written with everything as “exported types” which causes some file types to not get recognized by OS X.

that bug have been removed in the current Xojo release.

I typed this bug # in Feedback and get “No Results Found".

What I wanted to know is… which previous Xojo version suffer from this bug ?
(and, eventually, how can I know I have this trouble ?)

This entry in Feedback says that it is only visible to alpha and beta testers.
