Loading 3DS files

Hi ! I''d some problems when I tried to load misc .3DS objects in my 3d engine : In some files ( quite rarely ), objects don''t appear to be at the right location.. I first thought it was because points were set in the local referential of the meshs ( given by chunk 0x4160 ) and not in the global referential of the scene, but when I did the transformation, it didn''t changed anything.. Is there another chunk setting the object''s position ? I could give a link on .3DS files if needed ! Thank you !
