If you define a select_1 question with non-numeric option values, the reviews are not displayed.
Do you want to import or export the specimens?
$ans = select_1
! The specimens are to be imported.
! The specimens are to be exported.
In this case, ask_tty will not display the review message. If 'i' and 'e' are substituted for '1' and '2' , the reviews are displayed correctly.
I haven't tested ask_wx or select_n questions which may also be affected.
