Crashes when returning from screensaver with "Blank Screen Start Command" enabled

[Ahchay]

I am using the Blank Screen Start Command feature to run the following powershell script on my Windows build:

powershell (Add-Type '[DllImport("user32.dll")]^public static extern int SendMessage(int hWnd, int hMsg, int wParam, int lParam);' -Name a -Pas)::SendMessage(-1,0x0112,0xF170,2)

This works correctly (turns off the monitor), but when I attempt to wake up the PC, the monitor turns on but AttractMode is hanging on the last slideshow image that was being displayed. Eventually, if I attempt to exit AM, then the Windows "This program has crashed" dialog will be displayed.

Further info: Get this message on the console screen when trying to 'wake'

AL lib: (EE) ALCwasapiPlayback_mixerProc: Failed to get padding: 0x88890004

Might be an issue with PowerShell not terminating/returning control

Have worked around by using MultiMonitorTool from nirsoft.net
