In Microsoft Windows 2000, Microsoft Windows XP, and Microsoft Windows Server 2003, when you click either Continue or Try Again in a MessageBox control, the MessageBox function returns an incorrect value.
Note The MessageBox function returns correct values when you only use the MB_CANCELTRYCONTINUE flag without using the MB_SERVICE_NOTIFICATION flag.

This problem occurs when you use the MB_SERVICE_NOTIFICATION|MB_CANCELTRYCONTINUE combination of flags to call the MessageBox function.

To work around this problem, use another three-button MessageBox flag. For example, use the MB_ABORTRETRYIGNORE flag together with the MB_SERVICE_NOTIFICATION flag when you call the MessageBox function.
