Hi MarleneM,
Once the trace route command completes and the results are displayed in the Command Prompt window with the black background, you *should* be able to select all of the results by right clicking within the box and choosing "Select All", then copy them by holding down the CTRL key on your keyboard and pressing "C".
I am not quite sure what might be causing that window to close spontaneously but, if you cannot get the method described above to work, you could also try taking a screen shot of the results by pressing the “Print Screen” button along the top of your keyboard as soon as the results are displayed.
Once you have done that, you would then want to open Paint (which should be located in the Accessories section of your All Programs list), paste the screen shot into that program, and then save the results as a JPG file.
If you end up getting a screen shot of these results, please ask for an email address that you can send the trace route to when you open your support case to and you will then be able to email the JPG file containing the screen shot to us as an attachment.
