I must have a setting somewhere that is doing this to me. Every time I download a *.rar file, Stuffit Expander (and every other expander I have tried) immediately and automatically tries to expand it. There seems to be no way to shut off "auto-expand" on any of the expander programs, so I must have mistakenly set up something in the OS that is doing this to me. It's really annoying when the expanders try to expand a multi-part file when only the first .rar has downloaded. Any ideas? Thanks!
