Hi.<br><br>(I already responded via e-mail, but thought I'd post here too for others).<br><br>Ping Plotter doesn't strip off all the protocol prefixes, so you need to do that yourself. For example, if you want to trace to the address: http://www.nessoft.com/, then you want to strip off the http:// and use just www.nessoft.com. <br><br>Also, if you enter a name that can't be resolved into an address, it doesn't get saved into the history list (it thinks that you entered an address in error and wouldn't want to save that).<br><br>Thanks for the question!<br><br>Pete<br><br><br>
