I think your original location of AfA_OS_Loader in s-s was correct. I mean on my system I run it right after C:AddDatatypes command and before VisualPrefs and IPrefs and everything works fine. However, disable PowerIcons as this patch is not needed anymore with AfA_OS. In addition, try to remove picture_datatype.exe and ilbm_datatype.exe from AfA_OS_Libs: directory and reboot. While this new picture datatype replacement supports alpha channels and other features, it might not be compatible with your system.
