I tried the latest development release
it still crashes out for me when doing big scans. If this is not what
you mean by r21875 could you point me in the right direction to find it?
I have noticed with this release it is using more CPU power, spiking up to
60-80% but eventually coming back to 50% where it is hanging and not

Guys, I think this is greatly ameliorated in r21861. Please give it a
try. I made it update the text field incrementally, and also apply
highlighting incrementally. I can "nmap --packet-trace -p- localhost"
without much delay, with highlighting on.
I'm guessing you might not have tested the new incremental update
code on Windows (it works as before/expected on Linux), as I don't
get to see any scan results until the entire scan has completed. The
highlighting seems to work fine though (from memory it looks
identical to before), and it didn't freeze/crash.
You're right, I didn't test it on Windows. It didn't work for me either
when I tried it. I did something different in r21875, please try it.
It appears to be working much better on Windows, many thanks for fixing
I'm now able to complete a -p- scan with --packet-trace (using the same
host where Zenmap would freeze before). The CPU usage tends to briefly spike
as updates are made, and roughly doubles with highlighting enabled (towards
the end it was briefly maxing out one of my cores during the spikes), but
unless you're using --packet-trace it's probably now fine for most systems
