An SIT is expandable through UNSITI.EXE, but not the SFX version. The underlying file is a MacWord 5.1 doc that wouldn't convert cleanly with W4W 2.0c (and Word 6.0 is, according to Gateway, on it's way .. but not here, yet). When it gets here, I'll attempt to convert it again. In the meantime, if you'd like to play with the conversion yourself, I'll shoot you a SIT version.
