It would appear that after creating an Image with Composer, and then deploying that image with Casper Imaging, breaks files used with the built in Mac OS "Archive" utility.
The Error:
Unable to unarchive "NameOfFile.zip" into "Directory"
(Error 1 - Operation not permitted.)
What we've tested thus far:
A fresh install of Snow Leopard 10.6.3 allows the unzipping of files. No updates, no additional programs installed, no modifications except for an admin account.
We then create a new image and deploy it, and the Archive utility fails to work.
