Behavior of click() method

In IE, the click method does not work simply.
The first click gives the control focus, and the second click raises the click event.

The first click sets the focus to the control.

The second click raises the click event.

In IE, click the Tools button, select Zoom in the menu and tap Custom in the sub-list.

Button

It is not clickable. The control does not get focus.

Modal dialog

Click “Menu1" to display the JavaScript Alert dialog.
The Alert dialog is modal.

There are two types of dialogs in IE on Windows10. The dialog will be displayed with a checkbox when displayed several times.

That has a checkbox and the following message.
“Don’t let this page create more messages"

Button

The result is different between “with normal" and “with checkbox".

Dialog with normal

If Selenium clicks the “submit" while the Alert dialog is displayed, the dialog will close and an exception will occur.

Selenium cannot get the element. An exception occurs.
