Just had this happen today for the first time. I had ping plotter running for 7 hours (tracing at 1 second intervals) and when I moved the graph at the bottom to the left, I noticed that when a certain part of the graph was displayed (where the "notch" is in the bottom graph in the image below), the entire graph would turn almost completely black.<br><br><br><br>If I moved the graph to the right, it would return to normal just as the "bad" part of the graph disappeared to the left (notice the times at the bottom of the graph).<br><br><br><br>I have a sample set and a "copy as text" of the entire trace session if you'd like to see them.<br><br>Jason<br><br><br>

Hi Jason.<br><br>Can you e-mail me your sample set, please? I suspect that this happened because of a change in your computer clock, but a look at the sample set can allow me to confirm this (or not!) and reproduce this issue on my PC.<br><br>Thanks!<br><br>
