    I have a dual monitor config (LCD with keyboard and for the secondary display a CRT with gamepads in front of a sofa. IR Server /MCE Remote is used to control MP, and by pressing the Windows Start button MP starts on the secondary monitor. MP is never minimised. That part and MP itself works very well.

    Now after doing stuff on the primary screen (causing window focus to change) and then starting MediaPortal.exe again while MP is already visible, the already runing MP instance is activated but fails to get the focus. Instead its taskbar button is just blinking.

    This is probably caused by not calling allowSetforegroundwindow() in MediaPortalApp.ActivatePreviousInstance() or MediaPortalApp.SetForeGround().

    I haven't tested this by building MP itself, but when I use ChangeDisplaySettings.exe ( ChangeDisplaySettings , build required) to call allowSetForegroundWindow() and execute mp.exe the already running instance of MP is becoming the foreground window instantly.

    Cheers, Jenz

    Problem solved

    It toook me a time to realize the problem. It's caused by using IR-Server Suite to launch MP. Because IRSS might not have the right to set the foreground window, MP also won't be able to become the foreground window.

    Solution: here in this IRSS thread

    Cheers, Jens
