I have the power options for "choose when to turn off your display" set to 10 minutes on my Windows 7 machine. Every time I run Parallels Desktop for Windows and Linux 4.0 on that machine, it interferes with that power option and the display stays on indefinitely. This occurs even after I shut down Parallels Desktop. I have to reboot the machine in order for the power option to take effect again. Is there a way to fix this to prevent it from happening?
