Double-clicking only happens when you press the mouse button twice quickly enough. If the second press is too long after the first, you’ll just get two separate clicks, not a double click. If you have difficulty pressing the mouse button quickly, you should increase the timeout.

如果您想单击结果变成了双击，甚至您增大超时还这样，可能您的鼠标有问题了。试着接个别的鼠标到机子上，看看是否工作正常。另外，也可以把您的鼠标接到其他机子上，看看是否还存在这个问题。
