I haven't heard from Dan lately. I hope all is well!

V6 spent years in beta. There are two ways to look at that: first,
the compiler is perfect or, second, it wasn't a priority. Well, we
know it isn't perfect. I guess I just got put off by the amount of
time it spent in beta with no apparent effort to move it forward.

OTOH, V5 with all its' warts is a known quantity. It has been around
since Win95 and, while it lacks the newer objects, it is a lot more
stable.

I haven't spent ANY time looking at the new objects because I don't
plan to upgrade to V6 any time soon. Maybe if I did some reading, I
would get motivated. Or not... It's frustrating when things don't
work. oEvents comes to mind.

I don't have the sonar device and there could be issues with the two
pin approach. Ordinarily, I would solve that by using either one pin
or at least turning the output pin into an input so it would float
when not pinging. But I have no idea how it is actually
implemented.
