Recently i find out that maybe after installing some updates, my Excel 2003
has this problem:

1) When u open excel, with default Book 1 workbook at the background. If you
proceed to click the new workbook button, the excel will stop working with
the vista error message to check online for suggestion will pop up.

2) When you open 2 workbooks and arrange tiled side by side. It is still
able to allow you to do so. But once when you start copying data from one
worksheet to the other, the same error message as above will pop up.

Have done the following troubleshooting:
A) Repair the office application to no avail.
B) Uninstalled and re-installed the office application to no avail also.

Any kind soul would like to offer his kind help for me to solve this problem
will be very much appreciated.
