I think I am one of thousand people who upgrade MS Office to be MS Office 2007 and got pain for MS Excel to slow open file. It takes more than 1 minute. although there are no any add-in was installed and my file is very small in KBs.

HENCE, MY SOLUTION FOR THIS PROBLEM IS JUST INSTALL AN ADD-IN OF EXCEL 2007. You did not need to install all add-ins. Just install only one add-in and see the effect.
