Worksheet activate not called when starting workbook?[SOLVED]

[opus]

Hi,
I'm trying to show an Userform whenever a specific Worksheet is activated.
That works fine if I activate this sheet coming from another one of this workbook.
But the event is not called when opening the workbook, although the Sheet in question is shown . ?????
What am I doing wrong?

You're not doing anything wrong - it looks to be a bug with Excel.

I've just created a messagebox to appear on the workbook's open event & it appeared after the worksheets were all created, so it looks like you could bypass the worksheet_activate event and use the following code in your case:

Private Sub Workbook_Open()
    UserForm1.Show
End Sub

Thank'S Alex,
I figured to the same "workaround"
