SYMPTOMS
A text string on an ANSI single line edit control is not selected correctly, when the string is scrolled from the end of the string by using a mouse.



CAUSE
When you use a mouse to select a text string, the selected position range is calculated with a mouse POINT structure. If the single line edit control is an ANSI control, the selected position may point to a DBCS trailing byte on the string. If this occurs, the edit control must adjust to a DBCS leading byte, but the single line edit control does not properly interpret it.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
