Thanks for clearing the screw thing up for others--when I actually looked at the cart, I realized there are two screws of an unusual configuration (not slotted, not philips but two small holes in the round head--looks more like a button than a screw head).
Further research indicates that some owners have discussed this elsewhere. Good to know that it's actually the importer/distributor who is "suggesting" this mod rather than just some unknown tweaker.
