* Version: 1.1.1 (14 December 1993)
*
* Incorporates a bug-fix by Annard Brouwer <annard@stack.urc.tue.nl>.
* The nextText outlet of the findTextField was remaining set to the
* replaceTextField. When the replace controls were hidden, this
* caused the Tab key in the findTextField to appear to do nothing.
* The text in the field is now correctly selected when the Tab key
* is pressed.
