After a long experience using outlook 2007 I now have two problems:

Email Duplicates;

My hotmail POP3 account inbox has lots of duplicates. I just purchased the Sperry Duplicate Remover, and it cleared a GB of them. The next day when I booted the computer up, Outllook 2007 downloaded them again. My comcast account is not doing this.

Multiple Outlook Instances Running:

Outlook freezes sometimes after hitting the send email button. Task Manager shows two instances of Outlook running, but just one has an open window. Killing the first one in the list usually causes the one in an open window to unfreeze. What is causing it?
