I wanted to send some code to a friend via email. I sent it to myself first to make sure I was doing it properly. When I opened the file from myself I received a security warning stating "The publisher can not be determined due to: Authenticode signature not found." It then gave me the option of opening file, getting more info., or canceling. More info. did not help. When I choose open, the file opened for maybe a 1/4 of a second and then was gone. I tried several more times, but achieved these same results. Anyone know why this happens, and how to fix the problem?
