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.
