Thanks to those of you who replied re the 10.1 problems, It occurred to me what the problem might be -- the default install location is /Applications/Doggiebox, and since the Applications folder is owned by an admin group, the installer might have had problems writing there without authenticating as an admin. Anyway, I've also realised that there are other implications with using the PackageMaker-built installer format; for example the system keeps a record of the installed package and its version, and will warn you with subsequent installs if the version numbers conflict -- even if you've deleted the package and its related files from your system in the interim. So the upshot is, I'm just going to Stuffit everything (like with all previous builds) in the future. The Installer package was an interesting experiment. :) Meanwhile you can safely do this from a Terminal to get rid of the installer package detritus, if you desire: rm -Rf /Library/Receipts/Doggiebox-1A7.pkg -ben -- Ben Kennedy, chief magician zygoat creative technical services 613-228-3392 | 1-866-466-4628 http://www.zygoat.ca
