These comments apply to any dialog.  A direct method is to fiddle with the
editField in the DialogRecord.

A better, more compatible way (IMHO), is to call HideDItem and ShowDItem.
If the item you're hiding is the current editText item, HideDItem either
moves the insertion point to another editText item or gets rid of it if
there aren't any others. 

Yes, I confess.  I know this because I've abused the Dialog Manager in the
past with some dynamic dialogs - not because I know IM by heart.  :-)
