I just tried the following experiment. I used Apple's DiskCopy to make an .image file from an 800K disk. I compressed the resulting file with both StuffIt Deluxe and Compact Pro. Here are the results: StuffIt Deluxe - reduced the file from 838,843 bytes to 18,977 in 60 minutes (yes, one hour). Compact Pro - reduced the file from 838,843 bytes to 1,731 in 10 seconds! I realize that there are many tests in which the difference isn't so great, but isn't this a bit ridiculous? Rick Zaccone -- zaccone@bucknell.edu

Here is another tip: in the "Preferences" menu, make sure that the option "Allow Background Tasks" is OFF.

While I agree that this speeds up the compression time alot, I think it is Stuffit Deluxe's biggest shortcoming. It is virtually unusable in the background. At least in comparison to Compactor Pro. I think Aladin really needs to look at their model for background operations. I feel, IMHO, that the user interface of Stuffit Del. with the performance of Com. Pro would make the best product. I'm sure with future revision both the interface and performace of both products will improve.
