	[Failed attempts to lock text field in Chooser
	 dialog template using ResEdit.]

I don't think you can do this by modifying the Chooser dialog, but you
can certainly prevent the Chooser from modifying the user name string
in the System File.

Open the System file, or suitcase file, which contains the Chooser using
ResEdit.  Open the 'DRVR' resource named "Chooser" as 'GNRL'.  Make
the following change.

	A9E2 A9AA 4E5E 4E75  ->  4E71 A9AA 4E5E 4E75

This prevents the Chooser from copying the text from the User Name
editItem to the 'STR ' resource in the system file.  The user can now
change the User Name field in the box as often as he likes, but the
change never takes effect.  The LaserWriter driver, etc. will always
use the approved User Name.  You could initially set the user name
using some other method, since the modified Chooser no longer will do
so.

I recommend that if you actually do this, you rename the Chooser so
people know when they are working with a disabled copy.

This works with "Chooser" from System Tools 6.0.3.
