Expander fails to expand gzip files

Eric Hauptman, Aladdin Technical Support Consultant, confirmed to Greg Hartwig that StuffIt Expander 6.5.1 cannot expand gzip files: "Unfortunately, we introduced a bug in Expander 6.5.1 with regards to gzip files. We are working on a fix but at this time I have no release date. A temporary solution would be to use Expander 6.0 or 6.0.1 to expand your gzip files."
