Do you have any handheld deviced cradled? Do you have indexing on a desktop search configured to include Outlook? Do you have an antivirus program scanning the PST? If you open the Task Manager (Ctrl+Shift+Esc) and examine the Processes tab, do you see OUTLOOK.EXE there even when you believe Outlook is closed?
