I created some macros in a workbook but have since deleted them. I still get
the message when I open the file if I want to Enable or Disable Macros. Is
there any way to make the box go away since there are no longer any macros.

I know you can change the security setting, but when I send the file to
other people I don't want them to see the dialog box.

Thanks
