Good evening,
I have just switched from 2003 to 2007. I had some xls file and some xlsm. Now when I try to work within my spreadsheets I cannot type in anything... The columns are now numbers and the rows are numbers as well. What happen?

I was working on an important workbook with all my codes and now all is lost. They are there but they don't seem to properly work... I have enabled all macros so that is not the problem. Then after I try to insert information my Excel freezes...

Any idea of what happen?
