First off, which version of StuffIt Deluxe are you using? There are supposed to be speed improvements in 2.0 (2.01 is the latest); I have yet to find them... :-( Second, are you stuffing with "Best" mode? If so, TURN IT OFF! Use "Best Guess" only. The "Best" mode will try EACH of the compression algorithms and keep only the file which is smallest. As you might guess, it can take a HUGE amount of time to try all four options. I'd guess that is what you are seeing. Note that I saw this problem too (a 2.7 megabyte 4th Dimension database made StuffIt 2.01 appear to _hang_ my machine for nearly as long), and Aladdin let me know about the "Best" mode situation. Didn't spot _that_ useful tip in the docs. -- | Paul E. Jacoby, 3M Company | | | Maplewood, MN 55144-1000 | Parachuting?
