YAST Sys Admin from ASCII terminal

From my ASCII terminal, I am able to work with YAST (yast -m -t) for most things.

However, when I go into System Administration, User Administration or Group Adminstration, I am not able to save changes, get help or select existing groups or users. F1, F3 and F5 bring me back out to the System Administration menu. Any attempt to leave the screen brings up a dialog box that says that leaving the screen will cause all information on the screen to be lost.
