The protoPicker is a popup picker. Read the Programmer's Guide and
Reference. It is explained there why bounds is used for the system to
display the popup picker at the correct place from the parent's view
(a button or something).

You cannot "redirect" a magic pointer in NS. So what you need is to
clone stuff or be smart, for example like i++ that patches the NS
function DoPopup.

Is it Simon's code?
Ask him! :)
