I was using SystemTask as more of a waste some time here before getting to
the WaitNextEvent really, I was just hoping it would be process friendly.

I've programmed various machines and OS with differing process capabilities
but I will bear that in mind and it does explain why the system clock can
be frozen quite easily!

Yes, that is what is does, I have however since the last post traced the
problem to a degree anyway, I put it down to [1] the problem was when I was
running through the debugger, and [2] I have no mac UI of any sort as I am
using Think C's console (so I can printf and see what is going on), this I
believe was not supplying any events so the WaitNextEvent was just sitting

Anyway when my code is run direct it does appear to work, at least to the
degree I have it now, I still need to figure out sending and receiving data
and trying to work out why I can't get the resolver to work :-(
