I have a very strange issue with my application that is running in a captive account on the server and displays our company dashboard on a screen/PC in the main office.

First, the PC connects to the server via Terminal Services and runs in a Captive Account. The screen saver for the PC is disabled, and the dashboard and the PC run 24x7. Only the screen gets turned off (if the office staff remember!)

The application runs fine all through the day and keeps refreshing and generating its PDF of the screen without issue. Sometime over the evening, however, something strange happens and I cannot explain it. The visual element of the application (that is, the display to the screen) stops working. The application process is still running, and amazingly is still generating the PDF (correctly) of the screen that does not display anymore. The actual process is still running!

Have you ever heard of such an issue before as this application was fine when the charts were displayed using the standard Microsoft charting tools, but has started doing this since switching to Nevron Chart.

The application does nothing flash, all it does is retrieve the data from the SQL Server and then pump it into the data-charts. After a refresh it takes a screen capture and generates a PDF. All pretty simple and basic stuff.

I am confused as to why the display to the screen shuts down .... would the screen being turned off cause an issue? It never has in the past, but maybe now with Chart ??
