Thanks, will do.

And regarding Jeremy's note about the 2 libraries can't be loaded, those are 
Input Manager plugins that have nothing to do with my app.

But I'm happy to say that I eventually found the cause of my problem. One of 
the frameworks I was using was compiled using "i386 ppc" set as the 
architecture. Setting this to "Standard (32-bit/64-bit Universal)" and 
recompiling the framework fixed it. Xcode seems to launch the app in 32 bit 
mode whether its in Debug or Release (because I have the Active Architecture 
set to i386). When launched from Finder, the app launches in 64 bit mode, and 
since that framework was not compiled with the x86_64 architecture it screwed 
up the app.

Hope this helps anyone else that runs into this issue.
