Almost.  You can't see the edit field, but you can still
type into it.  Moreover, it's still selected when you call
up the Chooser, so any characters you type go into it by
default.

On my system (Mac II; System 6.0.0; Chooser 3.3), changing the type of
the dialog item from editable text to static text did the trick.  It
still shows up in the Chooser window (as white on black since SelIText
works on static text too, at least on my machine), and the cursor
still changes to an ibeam while it's over the text, but clicking and
typing don't change the string in any way.

You might want to test this behavior on all the models of Mac in your
labs.  It's an undocumentated feature that SelIText, which Chooser
calls on that dialog item, does something reasonable on static text
instead of, say, blowing up.
