| i have adapted the microsoft code in the help file to work from java. so far i have only tested this on vista but i think it should work on any windows box. it requires jawin dll and jar available at their sourceforge site - a link is in the code.
/*
* This file is heavily based on Jawin: <a href="http://jawinproject.sourceforge.net/" rel="external">http://jawinproject.sourceforge.net/</a>

* assumes ComfortSoftware keyboard is loaded...
