SYMPTOMS
After you install the Microsoft .NET Framework 1.0 Service Pack 3 (SP3), the Leave event for the TextBox control may not be raised when the focus is moved away from the TextBox control. Additionally, if focus is then moved back to the TextBox control and then you press the TAB key to move out of the TextBox control, the Leave event for the TextBox control is raised correctly.

This problem typically only occurs when the TextBox control first receives focus. When subsequent focus changes occur in the TextBox control, the Leave event is raised for every focus change.
