microsoft outlook 2000
I am using microsoft outlook 2000 on a windows 98 OS. When I receive mail, a picture of an envolope appears in the registry trey notifying me of new mail. After I open all new mail, the picture of an envolope remains in the registry trey. The only way I can remove it is by rebooting. Any ideas as to what is causing this and what I need to do to resolve it? I appreciate all help.
