It turns out that I can't provide an executable without the above
mentioned
hardware being involved. It all works when this hardware is taken out of
the
picture. I guess we know what that means. As it turns out the driver for
this
hardware had a bounding issue. Why it didn't show its self with 2.2.2 is
I 
guess mute. Sorry for the used bandwidth.
