Larry,

This may help track it down based on what I am seeing.  I don't really need 
the answers, but thinking through them may help point us in the right 
direction.

In the "View last 24 hours" 24 line display, what is the source for the 
24th, currently drawing, line?

What is the source for the previous 23 redrawn lines?

What happens to the data from the 24th line when it completes and the 
screen refreshes?

I am coming to believe that the data gap is being inserted during that process.

Thanks much,

Brett
