The mst# resource will allow MultiFinder to locate the “Open Archive…” command in the “File” menu of StuffIt. This will allow you to double click on a stuffit archive to open it in multi- finder even when stuffit is already open in background under multifinder. Which means NO MORE sorry I can’t do that messages from multifinder.
The mst# resource should be pasted into a copy of Stuffit. To do this select mst# resource, copy resource, close mst# resource, open copy of StuffIt, Paste, close StuffIt, Quit ResEdit.
P.S. If an Archive is already open then you still out of luck because StuffIt only opens “1” Archive at a time. (But if an archive was open then you would probably see the archive window anyway and wouldn’t be double clicking the archive)
