Excel 2003/XP Pro

Using the Windows Task Manager I seem to have a instance of Excel.exe that
will not go away. My Addin creates a second instance of excel, works some
code and then closes itself, or so I thought. The file closes, the instance
disappears and returns me to the original instance, but I recently noticed
that the windows task manager still shows a process (not using resources 00)
.. Even if i close the original instance the process list just drops from 2
excel.exe on list to one. Although i have tried numerous manual and code
methods for closing I can only clear the Task manager list by rebooting.

if i run ym code it creates a list item in task manager for each run, so
without reboot I can get a long list.

Should I be concerned? Am i missing something in the shutdown?
Have listed the basic code snippits below


Public XLNewSpecial As Object
Public XLUser As Object

Set XLUser = GetObject(, "excel.application")
' so I can call the original instance when needed

Set XLNewSpecial = CreateObject("excel.application")
Application.Visible = True ' along withother settings

'code here to do suff

'explicit closing code

XLNewSpecial .Quit
Set XLNewSpecial = Nothing


The code looks like it works fine with the exception that the Task Manager
will not release my special instance of Excel with out a reboot. to be
specific WTM shhows a process but not the application, after my closing.
