Problem with Excel 2007
 

Hi Everyone, It is my first time working on Excel 2007. I was working on a
project which I started on Excel 2003, I opened another project for reference
and when I returned to the first project all sheets disappeared. The only
accessible buttons on the toolbar are the Macro buttons. All macros are
still there and sheet names in the VBA are still there. Did I loose my work?

Thanks to all
