One time I didn't get the menu option (it just circled around showing my dead squad for funsies), but since restarting the game it hasn't done it since. I know it's not exactly the same, but it suggests that restarting should fix it.
If restarting it doesn't work, all I can suggest is checking the running settings (eg compatibility mode, patch no., admin etc), and if not there are mods (see Nexus & GameFront) for running KOTOR on newer systems as naturally there have been a few issues here and there.
