    Another unhandled exception

    Hello -

    I posted a NT 8 exception a couple of weeks ago.
    I can't find the post here's another:

    2018-03-12 08:58:38:689 Shutting down NinjaTrader

    There is nothing else in my Trace/Log files.
    This exception is at the core of your low-level libraries. They need to be re-written.

    I shouldn't get exceptions when shutting down. I don't think this is ready for General Release. I am planning on moving back to NT 7.0.

    mmeninger,

    Thanks for posting.

    In your previous post, it looks like we requested some files to assist with reproducing. However, it's not clear if we received these files on our end. Please see below:

    "I'd like to try to reproduce what you're reporting. To do that, I'll need your workspace and template files.

    You can send me these files by going to the Control Center-> Help-> Email Support
    Expand 'Other files' and enable 'Workspace files and UI settings' and 'Template files'
    Please reference the following ticket number in the body of the email: 1860052 ATTN Patrick G"

      Hello -

      Data sent. Please do tell me if you find anything.
      This is a very frustrating experience.
