Do you presume the reason is always valid?
Perhaps you might choose to look closer.

That was a bit trite...  unbecoming a seasoned it guy.

I'd be happy to send the trace to you if you want.
Just tell me where.
In fact, I can do one better -- I can send BOTH ends of the path.

I don't think so, that is a BAD idea..
Does the idiot engine light on the dash of your car tell you exactly 
what broke ?
Or does it just mean "Hey dummy, get a mechanic  to look"?

I also don't recall presenting a cause, just it's presence under VC.

   then you can easily get real happy.
If you want to read the stuff coming from the other end, wait till the 
clutter clears.
There *IS* a difference.

Just let me know how you would like to receive it.
