	Sorry, Jim, I couldnt reach you by e-mail. Thanks so much for
	this program! It really works! I think Steve is not the only
	one who is annoyed by dxwm behavior. Me too!

	I ported it to my evironment: DS3100, Ultrix Worksystem V2.1
(Rev. 14) XR3. In order this program to work here I had to make slight changes
which can be useful if someone will port it to similar environment.
Though this is 100% unsupported code, I want to offer a patch (just so)
:-)
