Hi Alan,
Where have you been hiding?
Re mach 4, this gets asked once in a while.... I'll point you to the latest thread on the topic.
http://www.calypsoventures.com/forums/v ... ?f=9&t=359
In summary:
a) there are very few mach4 users (rather tiny market right now) and the mach4 software is well, "incomplete".
b) Artsoft made technical choices that make it a huge amount of work to "port" any existing mach3 thing to mach4.
c) Final, answer: Maybe someday, if it ever makes business sense.. don't try to hold your breath between now and then.
