We are transitioning from Office 2003 to Office 2007 and doing it in
sections. However during this transition time and in the future when certain
documents are brought back to life, we have an issue with Excel 2003
documents in Excel 2007.

We've come across a couple Pivot Tables that work as expected in 2003, but
once opened in 2007 they don't appear at all.

We've tried a few different methods of trying to get the file to up-convert
to 2007 and still work. I do realize that pivot tables have their own
versioning in the files but why would this prevent viewing on 2007?

My question is, what is the proper method for up-converting to 2007? Are
Pivot Tables known issues for this? Are there work arounds?

Thank you for your time.
