Thanks s2ware for responding. Think Autodesk already confirmed this as being
a bug using an x64 os but you are welcome to test it.
Use AMSTLSHAP3D to create a steal member (doesn't matter which one you use).
Make sure OSNAP is on (end point, mid points, etc...)
Use AMPOWEREDIT to change the length of the member.
As you drag to a new length does the osnap snap to the member being changed?
If so, that is the bug. Makes it very hard to extend the length of a member
to another part because you are not sure if you snapped to the part are the
member you are editing.
