Post From: Application closes down on its own, out of the blue

It is highly unusual for Sierra Chart to crash (shut itself down).

Please do the following for us:
- Start the instance that is shutting down.
- In that instance select "Global Settings >> General Settings >> Log".
- On that tab find the setting for "Save Message Log to File" (it's at the very top) and set this to "Yes".
- Select OK to close that window.

When the program crashes again, then do the following:
- Open the file manager program and go to the main installation folder for Sierra Chart (typically this is C:\SierraChart, but you may have put it anywhere).
- If this was the sub-instance that crashed, then go to the "SierraChartInstance_2" folder. If you used a specific sub-instance number, then replace the last number with the particular sub-instance you are using.
- Then go to the folder named "Logs".
- In there find the most recent file that starts with a filename of "Message Log".
- Attach that file to this thread for us to take a look by following these instructions:
