I think you are confused, when ls is running it is actually looking if there are any sub-directories inside the newly created directory not the directory itself:
You mean it doesn't look above the newly created directory, only at, and below? Ok, ok, I see now. Yes, it took a minute to see how I'd gotten it to "work" in cases where the directory existed - I chose higher level directories to save typing, so they always had sub-directories for ls to show. Duh!
Here's how I solved it to get what I wanted:
Code:
	print -n "Name a directory that ought to exist: "
read dir

if [[ ! -d ~/$dir ]]
then
	print "Directory does not yet exist. I will make it so..."
	mkdir ~/$dir
	find ~/$dir -type d -print
else
	print "That directory does exist, as well it should."
	ls ~/$dir
	find ~/$dir -type d -print
fi

Seems to work:
Code:
$ ./newdir.ksh
Name a directory that ought to exist: Fun/Super/Duper       
Directory does not yet exist. I will make it so...
/Users/rick/Fun/Super/Duper
$ ./newdir.ksh
Name a directory that ought to exist: Fun/Super/Duper
That directory does exist, as well it should.
/Users/rick/Fun/Super/Duper

I should've done that in the first place - because that's what find does. I still feel a little intimidated by find, but it always turns out to be incredibly useful. I really need to learn that command.
Thanks, everyone!

__________________________________________________________________________________________________________________________________________________

NAME

       tk_chooseDirectory - pops up a dialog box for the user to select a directory.

SYNOPSIS

       tk_chooseDirectory ?option value ...?
_________________________________________________________________

DESCRIPTION

       The  procedure tk_chooseDirectory pops up a dialog box for the user to select a directory. The following option-value pairs are possible as
       command line arguments:

       -initialdir dirname
	      Specifies that the directories in directory should be displayed when the dialog pops up. If this parameter is  not  specified,  then
	      the  directories	in  the current working directory are displayed. If the parameter specifies a relative path, the return value will
	      convert the relative path to an absolute path.

       -mustexist boolean
	      Specifies whether the user may specify non-existent directories.	If this parameter is true, then the user may only select  directo-
	      ries that already exist.	The default value is false.

       -parent window
	      Makes window the logical parent of the dialog. The dialog is displayed on top of its parent window. On Mac OS X, this turns the file
	      dialog into a sheet attached to the parent window.

       -title titleString
	      Specifies a string to display as the title of the dialog box. If this option is not specified, then a default  title  will  be  dis-
	      played.

EXAMPLE

	      set dir [tk_chooseDirectory 
		      -initialdir ~ -title "Choose a directory"]
	      if {$dir eq ""} {
		 label .l -text "No directory selected"
	      } else {
		 label .l -text "Selected $dir"
	      }
