I have a file that contains code in the workbook open event.

I have been making periodic enhancements and am up to "version 18" of the
app I am creating. The workbook open event stopped running when I open the
file.

I stripped out the code and just put a 'msgbox "text here..."' call in the
event to just see if it fires off. It does not. All sheet_activate events
still work. All macros run, including workbook_beforeclose, but not
workbook_open.

The workbook_open event still operates as expected in other workbooks,
including "version 17", and un-related workbooks.

I created a brand new workbook, copied version 18's sheets, modules, forms,
names and properties over, and the workbook_open still doesnt work.

Searched the KB, and this is NOT a workbook.open call. I am just double
clicking on the file in windows explorer to start (and my shift key is not
stuck down).

Any suggestions would be appreciated greatly.
