Help with ActiveX Listbox control in Excel

Hi,

I’m experiencing some annoying problems with activex listbox controls that I’m hoping someone with greater experience than I can help me out with.

I have an Excel spreadsheet that contains an embedded activex listbox control. When the user makes a selection in the listbox, the Listbox_Click() event is triggered more than twice when I programmatically set the value of the listbox. In other words, the sequence of events are as follows:
1. User makes a selection in the listbox
2. Listbox_Click() event fires once and runs to completion in most situations. However, in certain circumstances, step2 repeats 5-6 times when I set the value of the listbox programmatically! This occurs even if the EnableEvents and EnableCalculation properties of the Application and Sheet property are set to False.
3. Focus and control returned back to Excel spreadsheet containing the control.

The code in the Click event is pretty simple:

Private Sub ListBox1_Click()

MsgBox "ListBox1 Click() Event Fired"

If ListBox1.Value = 0 Then
ListBox1.Value = 1
End If

End Sub

From the code, one would expect the Click event to be fired a total of two times: once when the user selects the first item, and second when the selection is changed to the next row programmatically by changing the value of the listbox. What's going on?

Relevant properties of the listbox are given below:
Name: LikeItemsListBox
Autoload: False
BoundColumn: 1
Enabled: True
LinkedCell:
Locked: True
Multiselect: 0-fmMultiSelectSingle
Textcolumn: -1
Value:

Any ideas?

Thanks a lot for your help.
