''Resolved''' or so they tell me... Could you try the nightly in "test mode". I would like to know what causes the crash. If you start a command prompt (ie. Start->Run, "cmd", ) and run the following:

 cd  nsclient++ /stop nsclient++ /test # wait till it crashes, and post the log to me (feel free to search replace out any IP/port/passwords). nsclient++ /start

The latest nightly has some changes that might change some "crashes" into proper errors (I have changed a few assets into exceptions). Nightly can be found under download and is called: NSClient++-Win32-20080728-2044.zip I have gotten reports that this new build fixes this issue so let me know if it remains if not I will release a bug fixed version in the next few days or so. // MickeM
