Hi David, Thanks for the response. No the problem does not happen when switching to the topology tab, I never get that far with the scans. It is just on the main results window. I've included the output.xml file and also an screenshot so you can see what is happening from a graphical standpoint as well as the xml. I forgot to add in my initial email that this is on Windows 7 pro 64bit. Once manually closing out the application after it becomes unresponsive the windows error is "NMAP front end results viewer is not responding".

However, Zenmap keeps on switching to "not responding", CPU utilisation jumps to 50% and the programme hangs until it is manually closed out. Iamnot scanning relatively large blocks of IP's when this happens and it can happen with as few as 254 addresses. This is the same problem I am having, sadly I can't find much more aboutitlet alone a fix:http://readlist.com/lists/insecure.org/nmap-dev/1/5994.htmlI am running it on Win7Pro, when I scan addresses individually or insmallchunks of 10-40 IP's it works OK, but I have thousands of IP addresses to get through and this is just not feasible right now. Is this a known error with Zenmap and is there a work around? Maybe I am doing something wrong?Do it happen only when opening the Topology tab? That's a known user of CPU and memory. Maybe you can send an XML file that demonstrates the problem? Just run your same Nmap command from the command line, adding "-oX output.xml" to save to a file. David Fifield
