I wonder if this could be a new feature (also known as a curse) introduced
by a windows or office update. Do you have your update thing set for fully
automatic, meaning that Microsoft can inject your computer with new diseases
while you're not looking?

I am actually having the same exact issue.
I have two workbooks - one is a master workbook sent to me by a customer
and
I need to paste information from certain cells into an existing workbook.
I
use keyboard shortcuts to move between workbooks as well as the copy and
paste shortcuts. In the beginning it works fine but as I progress, when I
change to a workbook, some cells are 'empty' and it takes a few seconds
for
the information to re-appear in the cells. Eventually, one of the
workbooks
completely locks up and I have to do an End Task.
These are the actions I've taken to try to resolve the issue but have not
had any success:
1- I've tried different files (so it's not necessarily this particular
master file).
2- I've also tried copying into a brand new workbook.
3- I've tried putting the information in one single workbook but
different
tabs and copying/pasting between tabs instead of workbooks.
4- Downloaded latest service pack (3) and any updates to Excel 2003
5- Un-installed/Re-installed Excel
6- Checked hardware (i have a 2.2 ghz Intel Centrino laptop w/ 4GB of RAM
and 70GB of HDD free)

Please help!
