This improves the situation but does not solve it:

------------------------------------------------------

Private aValue As New String[]
Private hCombo As ComboBox

Public Sub Form_Open()

   Dim i As Integer
   Dim aList As String[] = ["aa", "bb", "cc", "dd", "ee"]
   Dim hScroll As ScrollView

   With Me
     .Arrangement = Arrange.Fill
     .W = 220
     .h = 500
     .Margin = True
   End With
   With hScroll = New ScrollView(Me) As "hScroll"
     .ScrollBar = Scroll.Vertical
     .Arrangement = Arrange.Vertical
     .Spacing = True
   End With
   For i = 0 To 20
     With hCombo = New ComboBox(hScroll) As "hCombo"
       .Name = i
       .H = 30
       .List = aList
     End With
   Next

End

Public Sub hCombo_MouseWheel()

   If Mouse.Delta Then
     Last.text = ""
     Stop Event
   Endif
   For i As Integer = 0 To 20
     If i = Val(hCombo.Name) Then
       If hCombo.Text = "" Then Return
       hCombo.Text = aValue[i]
       Break
     Endif
   Next

End

Public Sub hCombo_Change()

   aValue.Add(Last.Text, Val(Last.Name))

End
