No idea how to describe this problem, but just add this to a form :

VB Code:
  1. Option Explicit
  2.  
  3. Dim WithEvents Lst As ListBox
  4.  
  5. Private Sub Form_Load()
  6.     Set Lst = List1(0)
  7. End Sub

List1() is a control array created at design time. Error occurs :

459 - Object or class does not support the set of events
Anyway to avoid it?
