使用函数system（）时，无法捕获任何鼠标事件。 我已经知道system（）函数是一个shell命令，但是为什么使用此命令会阻止捕获鼠标事件？

#include <windows.h>
#include <stdio.h>
int main()
{
    HANDLE ConsoleWin;
    INPUT_RECORD eventMsg;
    DWORD Pointer;
    //system("mode con cols=140 lines=40"); //after using this function，I cannot catch any mouse event
    while (1)
    {
        ConsoleWin = GetStdHandle(STD_INPUT_HANDLE);//Get the console window
        ReadConsoleInput(ConsoleWin,&eventMsg,1,&Pointer);//Read input msg
        if (eventMsg.EventType == MOUSE_EVENT && eventMsg.Event.MouseEvent.dwButtonState == FROM_LEFT_1ST_BUTTON_pressed) {
            printf("Left button clicked.");
        }
        else if (eventMsg.EventType == MOUSE_EVENT && eventMsg.Event.MouseEvent.dwButtonState == RIGHTMOST_BUTTON_pressed) {
            printf("Right button clicked.");
        }
    }
    return 0;
}
