SYMPTOMS

Consider the following scenario on a Windows Vista-based, a Windows XP-based, or a Windows Server 2003-based computer that is running Windows Internet Explorer 7:
  • In Internet Explorer 7, you open an HTML page that contains a text box.
  • In the text box, you use the Japanese Input Method Editor (IME) to type some characters. Additionally, after you type the characters, you do not press ENTER for confirmation.
  • You click anywhere out of the text box.

    Note When you click anywhere out of the text box, the OnChange event occurs.
  • In the text box, you type to append some new characters.
  • You click anywhere out of the text box again.
In this scenario, the original characters in the text box are replaced with the characters that you append.

CAUSE

This problem occurs because the OnChange event is fired before IME composition is stopped. Therefore, IME receives incorrect information about the text range. This incorrect text range information causes IME to remove the original characters in the text box.

RESOLUTION
