Hi,<br>I have a slight problem here. I just installed ver 2.2. And I notice that in the log fie, the tracert result produces a N/A, and *. may I know what's the difference between N/A and * ?? Furthermore, in ver 2.2, the graph have a vertical line which is gray in color, and may I know what does the gray line represent? I have use 2.03 before and it doesn't have n/a result in the log and there's only black and red lines, no gray lines. Could someone pls assist me<br>Thank you very much<br><br>
