DescriptionThe ring Buffer that stores incoming mouse data has overflowed (buffer size is configurable via the registry).
Event InformationThis event record indicates that the Buffer that stores mouse movements and clicks filled up before you stopped typing. It means you entered data faster than the application could process it. Some of the data was lost.
Wait until the application has processed the stored mouse input, and then enter more data. Be careful not to work ahead too far. If you get this message often, the buffer size should be increased by editing Registry settings.
