I don't know if something got reverted, but no fix for VWR-1203 is in 1.17.2. diff ../../../linden.old/indra/llcharacter/llheadrotmotion.cpp llheadrotmotion.cpp (no difference from 17.0.12) There are no changes to llquaternion either that might have fixed it. It looks like it just didn't make it in, contrary to the release notes. -Jason
