> I took you suggestion, Andre, and tried to open multiple instances of vw7.6nc to see if I could get it to fail to start.  I wrote a shell script to open 20 instances simultaneously, and even after several script runs, 7.6NC opens fine every time.  And on the last run, I performed some menial tasks in each instance, like opening a code browser, etc, to see if each instance was useable, and they all worked fine.
