I am trying to test this. I downloaded a copy of my installer from the
internet, and ran it on a Leopard machine. The app I launched from the
installer crashed. But the 2nd time I run the installer (or just run
the app from the hard drive), the app launches and runs fine. Is that
the expected behavior?
I then tried downloading the installer again, and the app again launches
fine.
Does this sound like the "quarantined app" issue?
What do I need to change to force the system to view this as a new app,
so that I can test the effect of adding "xattr -d com.apple.quarantine
myApp.app" to my scripts?
Thanks in advance!

Someone mentioned the issue with not being able to call "open

downloaded from the Internet. I'm seeing the same thing with
launchctl.
Anyone know a way to launch your program after the install on Leopard?
Thanks very much.
The problem is that Apple attaches to those files coming from the
internet an extended attribute. Run this from terminal to see it
xattr -l myApp.app
Once attribute is removed with
xattr -d com.apple.quarantine myApp.app
You can launch it without user interaction.
Hope this helps,
Martin
PS.: Apple heavily uses now extended attributes for various things in
Leopard.
