Share a workbook
 

I am working in Excel 2007 in workbooks created in 97-2003. When I try to
share the workbook, the program goes the motions then gives me a message the
workbook is no longer shared, and I can't do anything in the workbook. I
close the workbook out and reopen. Then I am back to square one. This is a
new problem since I converted my Office to 2007. Any ideas what may be going
on?
Thanks
