Mouse click doesnt work in Lobbies/Channels

[Abdoghatrify]

Hey, Im having a problem with a bot i have made long time ago. It used to work until 2 days ago; Mouse clicks stopped working in game lobby, channels, server select, etc.. but it still works in game

that's the code of my click ( direct input )

    INPUT input;
    input.type = INPUT_MOUSE;
    input.mi.dx = 0;
    input.mi.dy = 0;
    input.mi.dwFlags = MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP;
    SendInput (1, &input, sizeof(input));
    Sleep(5);
    input.mi.dwFlags = MOUSEEVENTF_LEFTUP | MOUSEEVENTF_LEFTUP;
    SendInput (1, &input, sizeof(input));

Note: after finishing some games, with luck, the click works in the room lobby and keeps working untill i restart the game
