If you use ResBundle, it just keeps spinning its wheels, trying to open the data fork.
If you use ResourceFork, the following error message pops up:
The 'dsig' resource ID = 128 could not be saved because the resource could not be opened.
Do you want MissionComputer to try again?
By the way, the file is a plug (Windows or Mac, I am not quite sure) that was zipped, then sent as an attachment from a Hotmail account to a Lycos Mail account. It was then unzipped with Stuffit Expander 7.0 on a Mac running Mac OS 10.2.8.
I am trying to be as detailed as possible for the benefit of David Authur.
