If the item is an editText item you should also change its type to a
static text item. This should prevent a tab from moving the insertion
point to the grayed out or invisible item; notice that it may be a
little trickier do keep the item from responding to tabs than just
changing its type. The routines Hide/Show DItem don't move an item out
of the dialog's visRgn, they move it out of the dialog's portRect.
