Now, the message box is showed activated (the expected behavior) This isn't related to Python specifically: ctypes is just handing the values you pass straight on to the underlying DLL (here: user32.dll). If you check the MSDN page for the MessageBox function: http://msdn.microsoft.com/en-us/library/windows/desktop/ms645505(v=vs.85).aspx you can see there's a MB_SETFOREGROUND flag with value 0x00010000L which seems to do what you want. Why the Message box is activated the second time when it isn't the first, I have no idea. But it's Windows which is deciding what to do there, not Python. TJG
