When I receive an attached document (Word or OpenOffice), I click on it. I get a Norton Antivirus window that says it's clear and I click on the yellow Download button. Then nothing happens. 1. I don't get the windows that asked Open? or Save?. 2. The documents are not in the Download folder. 3. I reset the downloads to my Documents folder - nothing appears there either. 4. I search my iMac with the file names, and no results show up.
