Random Crashes on Set State and Draw Line.

[JerryWar]

I have experienced random crashes with new version. One while changing the Symbol instrument settings in the Data window from "Instrument" to "CME ETH index " see below, the other is Failed to call onRender for chart object "Line" External component has thrown and exception.

Hello JerryWar,

Thanks for posting.

So that I may investigate I would ask that you contact me by email at PlatformSupport [AT] NinjaTrader [DOT] com. In your message please include a link to this forum thread and a copy of today's trace files. You will find these diagnostic files in the Documents > NinjaTrader 8 > Trace folder. I will need to review a copy of the files which are named 'trace.20170427.XXXXX.txt'. There will likely be multiple files for each day.
