Stuffit 9 is a piece of garbage.

I successfully decompressed this version (3.19.2005) using Stuffit Expander 7.0.3 (the one pre-installed with OS X 10.3). I've yet to find a reason to upgrade from Expander 7.0.3.

However... there were a couple problems with the included files, apparently caused by a developer still living in the OS 9 world. :o)

"MultiSpec Description" has no filename extension, which gives it a generic icon and no association with any application. Anyway, it appears to be a MS Word document. Opening it with TextEdit works.

"MultiSpecCarb3.19.05" also has no filename extension, thus it is represented with a generic document icon as well. This appears to be the application itself. I simply added ".app" to the filename and it now has the correct icon and launches ok under OS X 10.3.8.

The new 3.30.2005 version corrects the problem with the application file. Alas, the description file still has no filename extension. I suppose ".doc" would be appropriate. Better yet, provide a .rtf or a .pdf file. Also, there is no reason to encode an .sitx file with binhex (.hqx) as .sitx files do not contain a resource fork. The binhex encoding adds about 200Kb to the file size.
