Does anyone know how to set a tab-order cycle for Carbon framework projects?

The Email Formatter gives a nice cycle through the text fields when made in Cocoa, but in Carbon it's all messed up. Tab will carry you through the first 3 fields, then goes off into the static text areas and gets lost. I thought it was something I did wrong, till I built the project from the DL here, and it did the same thing.

The only workaround I can think of is to install another eventhandler to grab the tab keys and move the point to a new field myself, and this seems a lot of trouble I shouldn't have to do.

TIA
