NEOCOMSOFT  Rbonneaut, I definitely hear what you're saying about file size. The original Mac classic "Calendar 2.1" was 24 KB. That's one thing that impressed me about it. So much of Mac software these days is so huge. Sorry about the file size of Calendar 2.2. Most of that is actually the SuperCard runtime engine sitting underneath. Regarding the Supertalk error, I think it could be because this first version works only if the "Region" in the International pref pane is set to United States. But if that's not it, give me an email and I'll see if I can fix it for you. neocomsoft@thalo.net
