Hi Charlie, OK, after installing 2.5.7, I notice: NUnit hasn't (in about 1/2 a dozen tries) been unable to find my tests -- they all seemed to run correctly. After the first run, however, 'nunit-agent-x86.exe' was left in my Process list. After that, each subsequent run seemed to start (and later kill) a new instance, while leaving the first instance running. Once, I tried Stopping the tests (from the GUI) before they completed. That time, another instance of 'nunit-agent-86.exe' was left behind. The next run still seemed to run OK, however (starting and then killing a new (third) process). Now, I have no NUnit running, but two 'nunit-agent-86.exe' processes still running, according to the Task Manager. I've never seen an instance of 'nunit-agent.exe' while doing any of this. Hope this helps, --Chris (BTW, I used to be able to put breakpoints into my tests (and into my code base) that would get hit when NUnit ran the tests. Now, they don't get hit, and VS says that 'No symbols have been loaded..' when NUnit is running. Is that an intended change? --cs) -----Original Message----- From:
