Thank you again Peter. I have contacted support and chatted with Rajesh. Remotely he performed an entire cleanup. We uninstalled and reinstalled McAfee. i will not be able to state that it now works, untill tomorrow's update. (There must have been some updates for IE9, as i did a complete uninstall/resinstall a month ago for Site Advisor). So in order to close this ticket, i will need to check the status on 5/5/11. i will post the results as necessary.
Thank you for your patience....and.... WE HAVE "LIFT OFF"....! Everything is working as described above, so I believe this issue has to have been the IE9 installation which was after the the Site Advisor "fix" that caused the issue.
Thanks again to Peter and Rajesh for all their assistance in getting this issue resolved.
