I'm using XP pro and Excel-2007. Recently switched to Office 2007 (from Office 2003) and have the following problem when opening any Excel file:

When I try to open an Excel file, MS-Excel starts right away but it takes while (MUCH LONGER as compared with Excel-2003) before the file opens/gets displayed. BTW, I do not have any add-ins enabled.

Can anyone please help me solve this problem?
