I have my screen set to shut down after 10 min in Windows power settings. It is not happening. It is not set for sleep, just shutting down the screen. I am suspicious that BI is preventing this from happening, it is the only active application when the problem occurs. It also seems like it started when BI version was upgraded. I guess to be sure I should deactivate it and see what happens. Has anyone had a similar issue? If so what was the solution.
