I'm gonna take a stab in the dark here. Perhaps it's a localization
thing? (It's "Undo" for English, but not necessarily for anything
else.) Or maybe it's a keyboard shortcut thing (a la Windows'
underlined letters) from NextStep (if that had them)?

You should be doing something like this (in pseudocode):

- (BOOL)validateMenuItem:(NSMenuItem*)theItem
{
    if (theItem is some item I made)
        return YES;
    else
        return [super validateMenuItem:theItem];
}
