What should I do if the developer tool of IE8 crashes?

The developer tools of IE8 are quite useful, that is, sometimes there are problems,

 

The main symptom is: When you click the tool, there is an icon in the toolbar, but you cannot click it to display it,

Cause: For unknown reasons, the size of the window of the developer tool is set to 0, and the position is set to the upper left corner of the screen. It is out of the screen, so it cannot be seen, it cannot be moved.

 

Solution:

Right-click on XP to maximize

In Windows 7, you can use the Windows key (win key) + direction key to control the display of the window.
