Glad to hear you managed to get it working, however I would continue to experiment as you will lose some AfA functionality without all the libraries in place.
Actually, i would recommend to Craven1200 to remove picture_datatype.exe and ilbm_datatype.exe from afa_os_libs directory, because they are buggy and cause a number of problems. mainly slow-downs.
I need to mention that i haven't try the last 2 updates though, but judging from the changelog, the problem should be still present.
As for the exec_lib.exe, i never had any problem with it.
Btw, does anyone know what kind of extra things this library offers?
