    Dim myBookMark as String

    Data1.Recordset.Index = "{Table Index Name}"
    Data1.Recordset.Seek "=", DBCombo1.Text

    myBookMark = Data1.Recordset.Bookmark
    Data1.Refresh

    Data1.Recordset.Bookmark = myBookMark
    DBCombo1.ReFill

Steps to Reproduce Behavior

Before beginning, make sure that you have a Foxpro 2.x type table that has an existing index on the field that will be displayed in the DBCombo control.

1. Begin a new Standard Exe VB Project. Under the Project -> Components menu option, add a reference to "Microsoft Data Bound List Controls."
2. Add a new form to the project, and then add a Data Control and DBCombo control to the form.
3. Set the properties of the two controls to the following:

         Data Control:
                       Connect           = FoxPro 2.6;
                       DatabaseName      = {Path to the Foxpro Table}
                       DefaultCursorType = 0
                       DefaultType       = 2-UseJet
                       RecordSource      = {Table Name}
                       RecordsetType     = 0-Table
   
         DBCombo Control:
                       BoundColumn       = {Field From Table}
                       DataBindings      = Leave Blank
                       DataField         = Leave Blank
                       ListField         = {Field From Table}
                       RowSource         = Data1
                       Style             = 0-dbcDropDownCombo
   						

4. In the DBCombo_Change subroutine, place the following code:

         Data1.Recordset.Index = "{Table Index Name}"
         Data1.Recordset.Seek "=", DBCombo1.BoundText
   						

5. Run the project, click the DBCombo box, and change the selection so that the code behind the change event is executed. The first time this combo box is clicked, it behaves normally. Click the DBCombo control again and try to scroll upward through the list by holding down the mouse button. The DBCombo will begin an endless scrolling loop that never reaches the top of the list.

NOTE: In the above code, the text inside the {} must be replaced with the appropriate information from the Foxpro table. This should be the name of the field to display in the DBCombo control and the name of the index that will be used to search on that field.
