You've joined the ranks of thousands that have this issue. This problem showed up here in 1996 with Outlook '97. It was there in the preview version Microsoft handed out in a conference. They never squashed it in versions 2000, 2003 and my buddy claims it happens in Outlook 2007.

There are long discussions about it but a solid cure seems elusive. The most common cure is to uninstall ActiveSync and eject Outlook add-ons like Norton and others. But that's not an option for some.

-> If you feel it must be fixed then you have to get it's maker to fix it.
