Good point, are we talking about the arms or handles. I assumed he meant the handles weren't popping up to locked position which locks the arms. As you pointed out the handles never lock although they can feel like they're locked if the toad is applying enough forward pressure on the arm.
Hope it wasn't my misunderstanding that caused this long discussion of what should be a pretty simple process.
