Mac app icons

[FlexibleLearning]

Can anyone point me in the right direction, please?

Using 10.6.8 on a MacMini with LC4.5.2

The standalone icns icon set is not being copied
(contents:Resources:Standalone.icns is zero KB) but no build error is
reported.

Using IcoFX software that automatically generates a 1bit set for Mac icns.
Images included are:
32bit: 128, 48, 32, 16
8bit: 48, 32, 16
4bit: 48, 32 16
1bit: 48, 32, 16

I have tried restarting and zipping/unzipping to force a Finder refresh
I have tried omitting the 32bit 128
I have even tried an icns file that used to work before I got a MacMini

The Windows ico version displays fine.

What am I doing wrong?
