MORE INFORMATION
================

The online Help topic, Implementing the DBList and DBCombo controls, states that
the search argument is cleared when the user presses the BACKSPACE key. This
does not occur.

Steps to Reproduce Behavior
---------------------------

1. Start 32-bit Visual Basic 4.0. If it is already running, on the File menu,
   click New Project.

2. Add a Data and a DBList control to the Form1 form.

3. Set the indicated properties of the following controls:

   Control     Default Name   Property           Value
   -------------------------------------------------------------------

   Data        Data1          DatabaseName       BIBLIO.MDB
                              RecordSource       Authors

   DBList      DBList1        DataSource         Data1
                              RowSource          Data1
                              BoundColumn        Author
                              DataField          Author
                              ListField          Author
                              MatchEntry         1-Extended Matching

4. On the Run menu, click Start, or press F5. Type a character and note that the
   first author name matching the character is highlighted. When you press the
   BACKSPACE key, nothing happens.
