I logged in today, newly upgraded to version 0.9 and I checked if all the components of my lab were working correctly. All but my door was working fine. The door is a set of linked object and used a special script to open and close, relying on llSetScale(). The door would not respond. I reset the scripts on the linked children (the parts that used llSetScale() with no change.
I had another linked set with this problem as well, once unlinked , the scaling operations would resume as normal.
Hmm.... perhaps the scale undo and the scale on attached "fixes" had something to do with this.
Btw, this is scriptably scaled, is NOT an attachment, and is a linked set.
-Chris... ::very annoyed with the "fix"::
