you must specify a general explanation for the user and then one header for each text input box.
Example for a window with two text input boxes:
MainMenu: Options
PullDownMenu: _R_eport error
TextInputMenu2: Send an error report by e-mail
Text: Please give a brief description of the problem:
Text: _D_escription part 1 (header for the first input box)
Text: _D_escription part 2 (header for the second input box)
