I agree. If I ever feel that this is my pigeon, I will file a bug on it. I can't recall what the state is on Linux PPC - last time I tried to load a file, it did not work as well as the MacOS version.

I am fairly sure that nothing is swapped correctly, floating point values, Layer names and 32 bit colurs!
