I'm having some issues with CB crashing when working with senuke.
I have nuke running at 10 threads and set it to try CB 4 times in the senuke settings area.
To make things easier I took a screen shot of my CB settings.
I also have all captcha's selected.
It crashed about 3 times within 30 minutes but it doesn't seem to be consistent.
For this reason I have created a Feature Request thread as well: https://forum.gsa-online.de/discussion/1706/error-reporterror-report-sender
