2003, 2007

Why does Autofilter not work on a protected w/s even when "checked to allow" ??

On the particular w/s, I checked the dialog box to allow Autofilter.

Further, I used the following VBA resulting with the same problem:

Sub workbook_open()
With Worksheets("My Sheet Name")
.Protect , userinterfaceonly:=True
.EnableOutlining = True
.EnableAutoFilter = True
End With

NOTE: If I unprotect the w/s, I can toggle autofilter.

BTW, the workbook in question is saved as 2003 with 2007.

Any thoughts appreciated.
