This seems to work well. CBOsfrmTouchpoint8 is a combobox shortened to just the dropdown square. CBOsfrmTouchpoint14 is a textbox that makes up the rest of the space. Never say never:

  Private Sub CBOsfrmTouchpoint8_Enter()  

  If Me.CBOsfrmTouchpoint8.Tag = "Yes" Then  
  CBOsfrmTouchpoint14.SetFocus  
  Me.CBOsfrmTouchpoint8.Tag = "No"  
  Exit Sub  
  End If  

  Me.CBOsfrmTouchpoint8.Tag = "No"  
  Me.CBOsfrmTouchpoint8.RowSource = "XXX"  
  Me.CBOsfrmTouchpoint8.Requery  
  Me.CBOsfrmTouchpoint8.SetFocus  
  End Sub 

  Private Sub CBOsfrmTouchpoint8_GotFocus()  
  Me.CBOsfrmTouchpoint14.Width = 0  
  Me.CBOsfrmTouchpoint8.Width = 3420  
  Me.CBOsfrmTouchpoint8.Left = 8580  
  Me.CBOsfrmTouchpoint8.Dropdown  
  End Sub

  Private Sub CBOsfrmTouchpoint8_LostFocus()  
  Me.CBOsfrmTouchpoint8.RowSource = "XXX"  
  Me.CBOsfrmTouchpoint8.Requery  
  End Sub 

  Private Sub CBOsfrmTouchpoint8_Exit(Cancel As Integer)  
  Me.CBOsfrmTouchpoint14.Width = 3180  
  Me.CBOsfrmTouchpoint8.Width = 240  
  Me.CBOsfrmTouchpoint8.Left = 11760  
  Me.CBOsfrmTouchpoint8.Tag = "Yes"  
  End Sub
