You are a star,

Could it be checked before system sleep, what ever is causing it even the power button?

Yes. Code from line 414 to 461 does it. This is what you need:

Code:

OnMessage(0x218, "WM_POWERBROADCAST")

WM_POWERBROADCAST(wParam, lParam)

{
    If (wParam=4) ;suspend
    {        
        Process, Exist, xbmc.exe ; check if xbmc.exe is running
            If (ErrorLevel > 0) ; If it is running
            {
                ;your code
            }
        
    }    
}
