Ello again… What byte sizes does the ModifyProp() command need for changing HorizPot,VertPot,HorizBody,VertBody? Cuz in the command it says that these need to be 1 byte size in length, but in the PropInfo Structure the sizes need to be 2 bytes. Or does the ModifyProp() command have NOTHING to do with the PropInfo Structure? Thanx… David
