If I try to remove an item from a collection and immediately add another:

col.Remove anItem
col.Add anotherItem, Key

It causes an error.  However, if I put something in between, like

col.Remove anItem
MsgBox "Hi"
col.Add anotherItem, Key

IT RUNS !! ??

Is it the speed at which collection items are removed and added that
causes the problem ?  What can I do to correct this ??

What's the error? The code below should work fine with VB6/SP5
'==========
Private Sub Command1_Click()
   Dim kColl As Collection
   Dim i As Integer

   Set kColl = New Collection

   For i = 1 To 50
      kColl.Add "Item " & i, "Key" & i
   Next

   kColl.Remove "Key12"
   kColl.Add "Item 51", "Key51"

   For i = 1 To kColl.Count
      Debug.Print i, kColl(i)
   Next
End Sub
