Bugs Fixed by XBS110.DLL Version Number 1.00.0002
-------------------------------------------------
PROBLEM ID: 2186

    Relates to DBase III

    An update is allowed that violates unique index. Using the XB110.DLL
    driver that shipped with Visual Basic, it is possible to add multiple
    records that share the same unique index. The new version of the
    driver does not allow you to update the database with a record that
    contains the same unique index value as an existing record.

PROBLEM ID: 2390

    Relates to FoxPro 2.5

    A general protection (GP) fault occurs when updating the record
    immediately preceding a record locked by another user. The GP fault
    occurs in XBS110.DLL at 0002:11DA.

PROBLEM ID: 2418

    Relates to DBase III

    A unique index is corrupted after an update query. The symptom of
