I've just reinstalled Microsoft Office 2003 Pro and now encounter a problem
that wasn't there before -- and I can't fix. Excel won't let me install
(very simple) macros citing Security settings are too high and lack of
Certification. However, Word that was reinstalled at the same time will
allow macros to be installed and run without a problem. I tried setting
Excel security to LOW but it doesn't make a difference. Can you help.
