Locked Shapes Don't Work the Same as they did prior to V6

Locked Shapes Don’t Work the Same as they did prior to V6. In fact, I’d say locking is broken.

Try this: create 2 shapes by drawing a rectangle and then duplicate it. Lock one of the rectangles. Now select them both and try to use the Align Horizontal or Vertical buttons or the Offset buttons (with say a 0 offset)…

Nothing happens! OmniGraffle used to move the unlocked rectangle while leaving the locked shape where it is.

I think this is bug. Isn’t it?
