We are migrating from Office 2003 to Office 2010 and we have one user with workbook that couses problems.
The workbook is made of 31 sheets each with ~ 40X30 cells, no macros. The issue is that this workbook when open in Excel 2010 couses computer slowdown and eats more than 500 megs of RAM, when open in Excel 2003 it works smoothly (less than 50 MB RAM).
Unfortunetly I can't share this file (it contains confidential data).
What may couse this behevior ? Has anyone experienced similar problem ?
