HideDelay     := 400   ; 闲置多久隐藏（单位：毫秒）

; ----------------

IsScriptEnabled := false ; 默认关闭状态

; 退出时完美恢复
OnExit((*) => SystemCursor(1))

    ; 核心逻辑：只要不是输入框（IBeam），且到了闲置时间，就隐藏
    if (A_Cursor != "IBeam" && A_TimeIdleMouse >= HideDelay) {
        if (!MouseHidden) {

    } 
    ; 鼠标在动，或者是输入框，就立刻恢复显示
    else {
        if (MouseHidden) {
            SystemCursor(1) ; 全局恢复
            MouseHidden := false

; 💡 核心改变：用区间循环代替大段数字枚举，既干净又100%全局有效！
