When I'm done reading and sending mail I close Outlook (It's version 2003,
running under Windows XP) using the 'Close' button. After going through a
day of opening, checking and answering mail and then closing when done,
I've noticed that Task Manager shows multiple copies of OUTLOOK.EXE
running. None of them seem to be taking CPU resources, but they do have
memory assigned. During the day, I don't notice any error messages.
Everything seems to be working fine. There are no clues to indicate that
something hasn't closed until I try to re-boot the PC. Then I get 'not
responding' messages and have to an 'End Now' for each of the running
instances. Any ideas as to why this is occurring?
