General weirdness is always a pleasant change of pace. First things first, I'd upgrade to Carrara V2.1 Version 1 of Carrara had many of it's unique bugs squashed with the update. However, if that's not an option, try this: After placing all of the hooks in their correct location, select each one and and then go into the modeling room. It will ask if you want to "Edit Master" or "Create New". Choose New and then close the window and repeat for the remaining hooks. No promises but it's worth a try. I'd also suggest reporting it on Eovia's site in their Bug Report area. You may be requested to forward the file to them for examination. Hope it works, Mark
