I've been using sketchup for about six months now. I came across a unique problem with an object from the warehouse. I'm trying to scale the length down from roughly 10ft down to 7ft. When I do this it snaps back to 10ft and the position of the object has changed. Has anyone else seen this issue and what is the workaround?

Object: http://sketchup.google.com/3dwarehouse/details?mid=282874fa757c0dabca76c527f185435c&prevstart=0

Thanks in advance!
