- StuffIt Deluxe 8.0 caused a problem whereby applications would not  
run if they were expanded from archive formats that do not preserve  
UNIX file permissions. In earlier versions of StuffIt Expander, this  
problem did not occur because the UNIX "execute" permission was set on  
all files as they were expanded. StuffIt Deluxe 8.0.2 restores that  
feature. However, if you are certain that you do not want the "execute"  
permissions set, you can tell StuffIt Expander not to alter UNIX file  
permissions when expanding non-UNIX compatible file formats. This can  
be done in StuffIt Expander preferences by un-checking the box that  
says "Set execute permissions by default".

  The StuffIt X (.sitx) format does support UNIX file permissions,  
results in the best compression, protects files from damage, and is  
therefore the recommended compression format for archiving.

-----
So stuffit 8.0 is causing you the issue, upgrade to 8.02

----
Lately the finder now allows archiving, unarchiving of applications,  
they really using gnu zip to zip all the files/resource forks/meta  
data. However I'm not sure when I'll
migrate to that format since os-9 users require sit files.  (Assuming  
there are any os 7.x/8.x/9.x users around).
